Unable to use any Yung's mods in Arclight Fabric

[addstar]

I have confirmed that ...

• Arclight is up to date
• all dependencies are installed
• all plugins and mods are up to date
• unable to reproduce in Spigot
• unable to reproduce in Forge

Arclight version

Arclight arclight-1.20.4-1.0.3-SNAPSHOT-fc9d39e with Fabric Loader 0.15.6

OS & Java versions

OpenJDK Runtime Environment (build 17.0.10+7-Ubuntu-122.04.1)

Plugins and Mods

YungsApi-1.20.4-Fabric-4.4.2.jar

Description

Most mods are working great in Arclight, but any time I try to load YungsApi on Fabric (which is required by all Yung's mods), it fails with a heap of mixin errors. I've done some troubleshooting and tried to use different versions but they all have the same problem. Arclight also errors when only YungsApi mod is the only thing loaded (no other mods or plugins).

I don't know if this is just a problem with how the mod works or a compatibility/broken issue with Arclight. Mod works perfectly fine on Fabric 0.15.6 normally.

Step to reproduce

1. Add YungsApi mod to Arclight (no other mods/plugins)
2. Crashes on startup
