Hello!

I've been trying to play a 1.12.2 modpack, but it keeps crashing with ExceptionInInitalizerError. I tried repairing the modpack, nope. I tried repairing the installation, nope. I even tried making a new custom 1.12.2 Forge profile, still nothing. I'm pretty sure it's a Forge issue, so that's why I'm here. Log is for the version with no mods, as the main error is the exact same, only it gives me warnings for some mods. I can play vanilla 1.12.2, but I can't play Forge 1.12.2.

Make a test with installing xrandr

Thank you! That worked somehow. But how does that make it work?

Do you have multiple monitors connected?

No, I'm just using a laptop, no other monitors besides the one built in.

 Maybe it is a laptop thing - I have no idea
