I have no idea why. Crashes on startup of Minecraft. 1.16.5 Forge 36.2.34. Latest versions of both Mods.

crash report: https://paste.ee/p/0Oy2a

It looks like the mod called "Too Fast" has broken mixins. And for some reason its just deciding to explode when i register my network. Which shouldn't even be remotely related to the mixin that is exploding.

Interestingly I already removed that mod because it was causing problems during startup (during mixin injection). Even after removal, it is causing problems? I think my config is completely screwed up.

Its still in your mod list so it was installed at the time of that crash.
