I am only running the newest version of fabric api (fabric-api-0.58.0+1.19) and entity texture features (entity_texture_features_fabric-4.0.1)

Is anyone else able to replicate this?

I cannot replicate this does it happen every time? can you post the full crash log?

entity_texture_features_fabric-4.0.1.zip
can you try this version? the .jar is inside the .zip

I can this version as well, however I think the problem is fixed. I updated fabric api and played on 1.19.1 (previously 1.19) and the game launched (before it was crashing on launch). So fixed for now?

must be this is an issue with mixins at launch and should happen every time i'm guessing a corrupt download maybe
