Yesterday my game was completely fine, I had 30+ mods in 1.15.2 and it was running perfectly fine. Today I tried to launch the game and instanly crashed. I've done everything I thought of: reinstall minecraft, use another version of forge, increase the RAM allocated to minecraft... And it did nothing. Other versions are also not working.
Here's the log I think: https://pastebin.com/n18s905t
