About a week or so ago, I uploaded a mod pack of mine onto Twitch via Curse, and it worked perfectly fine. I also tend to always update the mod pack when I want to change a thing or two about it. In this case, I have two mod packs of the exact same. Modpack 1 is where I add/remove any mods and mess around with configurations for me to export and upload. Modpack 2 is the modpack that is uploaded onto twitch.
Now here's my problem. As of yesterday, Modpack 2 (the uploaded one) would just crash upon launch for whatever reason when I updated it, but Modpack 1 works perfectly fine with no crashes whatsoever. The only changes I made were two configurations on veinminer and I added a mod that is an add-on to JEI. I didn't know what the problem was, so I re-exported Modpack 1 with nothing changed and uploaded it. For whatever reason, it didn't export every mod and it was missing a couple of mods. I re-exported it a third time with a mod or so added, hoping it would work, but to no avail. Modpack 1 works completely fine while Modpack 2 crashes instantly even though they have the exact same files.
When trying to find errors about Modpack 2, the image linked is what I got. I have no idea what any of these problems here are. Can someone here help me figure it out?
The modpack is called Shanozia if anyone is willing to lend me a hand and help me determine why it's crashing constantly.
Errors I get when booting up the uploaded mod pack
Quick update: managed to grab a crashlog of the latest crash (like two minutes ago) of Modpack 2 and it gave me this. Here's my issue:
For one, Optifine isn't installed. I don't know why it's telling me it is, there's no trace of it on the modpack. Two, the file authlib is apparently the thing crashing my game, but a friend of mine said it's not from a mod, but an internal core of forge itself or something along those lines.
