I was trying to play 1.15 modpacks and whenever i press "play" on the minecraft launcher the launcher closes then a grey screen comes up then the launcher opens to tell me the game crashed. There was no crash log and this only happens with modpacks for versions above 1.12 which work fine but i wanted to play newer edition mods. Any ideas on why its crashing?
Vanilla forge worked!! I deleted all the mods that came with forge (not sure if that was a bad idea or not) but now it works! Thanks to youngtomlin , majestyc2k1 , and especially SuntannedDuck2 for your suggestions for possible fixes and as for SuntannedDuck2 thanks for giving an exact fix. It is unfortunate that twitch isn't able to work and this is more of a different platform than a "fix" but it still lets me play minecraft
Failed to find Minecraft resource version 1.15.2-20200515.085601 at C:\Users\Me\Twitch\Minecraft\Install\libraries\net\minecraftforge\forge\1.15.2-31.2.27\forge-1.15.2-31.2.27-client.jar
This is whats causing the crash apparently yet i cant find anything about "Minecraft resource version 1.15.2-20200515.085601" and i cant find any files named "forge-1.15.2-31.2.27-client.jar" i'm completely stuck and cant find any fixes that work online.
I can make the profile and then it brings me to the launcher and when I press start It closes the launcher flashes a screen for a very short time then goes back to the launcher and says the game crashed but i will try using a newer version.
My only guess to try is to backup your Twitch and reinstall it, or to try with installing Forge to the Vanilla launcher and copying the installed files to the Twitch launcher (I've done the same with Fabric to get it working that way before Fabric had a better workaround and I think Forge can read files that work on the Vanilla launcher still in Twitch but I don't know for sure).
Otherwise have you tried 1.13.2 or 1.14.4 versions of Forge in Twitch and still gotten the same result, or just installing 1.15.2 without any modloader installed? Otherwise my only guesses are that either something is preventing it, or you don't have enough RAM or something. Only guessing though I don't know for sure.
I used to have issues with Twitch with versions above 1.12.2 around 1.13.2 to 1.14.4 period but they soon worked it out or my system wasn't being too particular on it I assume. But I could link you to the files I have in my install folder that is the latest and see if that works.
You can get Forge for the Vanilla launcher (regular launcher, Mojang launcher, whatever you want to call it) by going to the official website here: https://files.minecraftforge.net/
Not surprised, I'd say ask Twitch support or just use something like MultiMC instead as MultiMC is the alternative I went for when the Twitch launcher wouldn't work for me: for creating different versions (old and new), making/importing modpacks and so on (only thing is I don't know about uploading them to Twitch as Twitch modpacks have a particular packaging way), if you want to take a look you can find MultiMC here: https://multimc.org/
