Minecraft 25w14craftmine was the April Fools update from 2025. I'm not sure if its an actual snapshot, but it has the snapshot nomenclature. Because of this, there might not be a solution to your problem.
Is there any reason your using that specific version?

4 hours later edit after testing and after doing other things was busy with:
OK so done some testing and it seems LambDynamiclLights (tried a few builds) is crashing or something else is asking for SpruceUI or Pride Lib and I can't find those at all. So not sure there but Voice mod, Fabric API, WI Zoom, DynamicFPS and JourneyMap worked fine.
Mod Builds I used:
Dynamic FPS 3.9.4 MC 1.21.5
Jade 25w14craftmine 18.0.3
WI Zoom 1.6 MC25w14craftmine
Lambdynamic Lights 4.8.4 1.21.5 (I disabled as didn't work I think)
Journey Map craftmine 6.0.0 beta44
Voice Chat 25w14craftmine 2.5.29
Fabric API 0.119.10+25w14craftmine
In terms of Fabric Loader as maybe the latest doesn't work, which i had happen when working out a modpack I had to use 0.17.3 as 0.18+ didn't work with some mods.
But I used 0.18.4, maybe Lambdynamic Lights build i used doesn't work with 0.18.4, that's likely.
I don't have a VR Headset setup right now (have one for PC yes). So you'd have to try there and see what happens through ViveCraft's settings and your VR Headset of choice.
With LambDynamicLights crashing I assume hmm maybe preference mods doesn't work as it was incompatible with some other performance ones but Dynamic FPS works fine.
Hopefully that helps. I used the latest builds of Fabric API and all the other mods. I tried 2 builds of LambDynamicLights and no luck. You don't really need the other that much do you? Any other brightness settings mod? Or other dynamic lights type mod?
Earlier post:
Did you check the tags for any marked as that april fools version?
Do you have Java 21?
What build versions of the mods did you use? Just the latest? Maybe try a build back or more? Try adding and removing mods one at a time and see what happens.
Most mods 'may' have support for April fools snapshots but most don't, you have to check version tags, guess builds made around the same time, that sort of thing.
I'll take a look and see what ones I can find from those release periods as I'm curious/like a challenge of making modpacks with compatible mods but I don't think a whole lot will be available.
Even making a modpack for before world gen changes to datapack form for 1.17 snapshots and 1.17 Pre-Release was interesting for me to work out even when following the snapshots closely back then.
Try any of these: https://modrinth.com/discover/mods?v=25w14craftmine&v=25w10a&h=true I filtered Craftmine and 25w10a (no idea how compatible they may be but I only filtered the mods, I didn't go to EVERY mod and filter EVERY tag of it as they may vary and that takes a while of links to each mod and this post would be longer then it needs to be, check and see what works, move things in and out of folders, try a few builds).
Don't just go for what interests you either, sometimes you have to go for what 'works'.
Some maybe for for Craftmine or OneBlockAtATime (I even have the Fabric API builds for them listed on the FTB WIki page for Fabric API, I know as I update and maintain it with build numbers regularly).
25w14craftmine: 0.119.8 (0.119.10 is the latest now, didn't realise that till updating it now, but older builds may help so try them out if need be) is the Fabric API build your looking for if you haven't tried it already. I'm pretty sure when I went checking for them at the time of adding latest builds and April Fools ones nearby or that I had missed.
Also I came across Fabric Loader issues sometimes using the latest, not always but sometimes it's fair to keep that in mind and go back a few versions and see what works.
Not always are there April Fools versions compatible mods. You can get some that may be close on prior snapshots (like 1 or 2 versions before the April Fools snapshot, I never tested mods on Craftmine or OneBlockAtATime but I did on the prior ones to those) or made for it but not always say they are but its very hard to tell.
Even if I briefly bring Legacy Fabric into things I know some may be compatible for that on older April Fools snapshots between the 1.3.2 to 1.13.2 range but even still I don't know how effective they are).
Otherwise there is mods that offer April Fools snapshot blocks to Release versions but not so much the more heavy tweak stuff which I assume many are more likely after with those snapshots.
Even Combat Snapshots I only know of Fabric API or Craft Presence as available not so much others but they are mod-able still.
Unlike 20w14Infinite which had many mods for it (even a modpack easily made for it).
Or some I looked into for 19w13b with Tech Reborn X or Roughly Enough Items Clownfish update.
Those were the ones I commonly remember Fabric support for, others not as much and were just 1 to 2 snapshots before and happened to work or didn't on the April Fools ones.
Your crash is from version mismatch. SpruceUI and Pride need Minecraft 1.21.5, but you’re running 1.21.6-alpha Craftmine, so Fabric can’t resolve dependencies. Either downgrade the game to 1.21.5 or remove LambDynamicLights (it pulls those libs). April Fools builds also have limited mod support, so only use mods tagged for that exact version.
Here is my testing (didn't label my builds in the prior post)
Otherwise who knows if the original poster responds or not but that aside.
Mod Builds I used:
Dynamic FPS 3.9.4 MC 1.21.5

Journey Map craftmine 6.0.0 beta44
Voice Chat 25w14craftmine 2.5.29
Fabric API 0.119.10+25w14craftmine
Didn't test the VR mod so I can't say for there.
In terms of Fabric Loader as maybe the latest doesn't work, which i had happen when working out a modpack I had to use 0.17.3 as 0.18+ didn't work with some mods.
But I used 0.18.4 Fabr4ic Loader, maybe Lambdynamic Lights build i used doesn't work with 0.18.4, that's likely. I didn't test for that as the others worked fine and I didn't care to test these for long anyway.
That can be true but I myself have tested many older snapshot or release builds versions of mods for compatibility and they can work. NOT ALL but some can. I literally did the testing myself in my post. I've done this from 1.14 to 1.17 snapshots. Literally even made a 20w14Infinite and 1.15, 1.16 and 1.17 Snapsnot to Release modpacks.
It all varies. Sometimes you can get one 'right for the version intended' but the code still doesn't work, so the version isn't really a factor. I've been working out tagged modloaders and versions and gone yeah that doesn't work. It happens.
The crash report may be correct of course and what they encountered that. I myself when I tested them (other then the VR one as I don't have my VR headset setup), worked fine, at least the builds i chose right on or one or two back.
It's up to them to respond as we haven't seen them respond yet (as many people do).
It's like with 1.9.4 to 1.10.2, sometimes they can work, other times not, other times like back then some needed the Compatibility Layers mod by McJty, other times not.
In terms of them missing versions yes sometimes that is the case, and in others they need to go for ones on craftmine or before craftmine builds not ones after.
hey i just went through the same thing with lambynamic lights and can confirm that 4.4.1 worked, for me at least. hopefully this helps someone else out there. i grabbed simply craft mine modpack on modrinth but a number of mods right out of the box were crashing it, which i couldnt quite understand considering its still updated pretty recently even. i can see why people still play it though haha
