the log from version 1.0.4 (1.19.2), crashed just at startup https://mclo.gs/tvZbjWb

If you remove MixinExtras, does it work then?

I can't exactly remove mixinextras, it was added by another mod and removing it probably breaks a ton of other mods.

It gives the exact same error with no other mods in 1.19.2 https://mclo.gs/V0HeIfw

Shows you are trying to 1.19.4 on 1.19.2

Just tested in a clean 1.19.2 build and it's loading just fine for me.

This was found to be the fault of mods that are using the beta version of MixinExtra instead of the release version. New version is pushed using the beta.
