The game keeps crashing with every Malisiscore version and both on Nvidia and AMD. This is the log pastebin https://pastebin.com/TWtvZJ3i

Duplicate of #162 , #173 and undoubtedly more. Issue is caused, as mentioned by an outdated version of Mixin in the mod itself. Ideally the mod author should remove the requirement, but as they're missing in action that seems unlikely. My own solution was to find mods that have mixin as well (as mentioned above) and rename either of them by adding '_aaa' to the front of the filename. So for example 'VanillaFix.jar' would become '_aaaVanillaFix.jar' That way it shows up first when minecraft processes the mods, and thus it uses the newer version of mixin. There's also a solution that requires moving mixin out of the jar, but can't remember exactly which file(s).

One of your mods is using an outdated mixins version, either downgrade this mod to an earlier version or update the other mod.

If you are unsure here are a few mods that ship with Mixins:
Dynamic Surroundings
Surge
VanillaFix
MalisisCore
Phosphor

This is by no means all of them, just some of the more popular ones.
