I think you need to update your Java

[Geolykt]

Thing is, shouldn't 1.20.1 run on Java 17 still? Looking at the minecraft wiki it's only 1.20.5+ that requires J21

That being said, this issue is unlikely to be caused by MixinExtras regardless.

If a modpack doesn't work out of the box that is more likely to be an issue with your local setup than with mixinextras. Feel free to reopen if there is evidence otherwise.
