It seems that a user tried to play on my modpack, and connected a Nintendo Switch Pro Controller and the game crashed. The fix seems to be to remove EmoteCraft.

Remove midnightcontrols

So the problem is Emotecraft's incompatibility with Midnight Controls? The user removed his mod and the crash was resolved.

midnightcontrols uses obsolete emotecraft classes

Then I'll report it to them.
