The error mentions this java.lang.ClassNotFoundException: dev.architectury.utils.fabric.GameInstanceImpl::init

Any ideas what might be causing it? I don't know if its architectury but that is the only mod I see mentioned. Just upgraded to architectury 5.11.38 still on fabricloader 0.14.8 with a few other mods

This is a bug in Server Translations API.

They're trying to read resources through the mod classes and assuming that all entrypoints are class names, but they can be method references like ours.

Ok thanks. I assume that is a module of fabric api and it will be fixed in an upcoming verison of that?
Edit: I thought it was bad practice to use STDERR lol

No, it's included within Hey That's Mine. If I remember correctly the devs of Server Translation API are @arthurbambou and @Patbox - report this to their repo.

Try installing this and tell me if it works https://maven.nucleoid.xyz/fr/catcore/server-translations-api/1.4.16%2B1.19/server-translations-api-1.4.16%2B1.19.jar

Server Translation API + Latest 1.19.2 Architectury loads fine for me. Additionally it doesn't have mixin under create method in language files. It might be interaction between some other mods you have. From what I can see it's issue with d4f (Discord4Fabric) mod. See https://github.com/Reimnop/Discord4Fabric/blob/main/src/main/java/me/reimnop/d4f/mixin/LanguageMixin.java
