Minecraft 1.12.2
Forge 14.23.5.2860
MixinBooter Version 7.1

Minecraft immediately doesn't get to launch after I press the Play button on the Minecraft launcher. It doesn't load up or anything.
Here is the log: https://gist.github.com/vainlaind4in/190c8ff5b57d76bd66cc95b5940a628f

Removed MixinCompat and Bootstrap and it still does not work and gives the same error. I also doubt it's a Java problem because I have a different modpack with a similar mods list, and that somehow works. Maybe it's some sort of mixin booter incompatibility?

Remove MixinCompat and MixinBootstrap and also update your Java and see if it helps.

Noticed this mod LootingModMC in the logs, can you provide me with a link of where you got the mod from? It's erroring.

I removed it and it started up normally. Thank you!

I'll note this down for future reference, seems volatile enough for it to crash with other mods also.
