Version-Loader

1.20.1-forge

Moonlight Lib Version

forge_1.20-2.9.7

Issue Detail

On startup, forge freezes and the attached logs are printed. The same version of fabric works perfectly fine, but for some reason it appears as if the forge mixin is failing to inject multiple messages similar to Invalid descriptor abcd Expected abc.

Log Attachment

latest.log

OPTIONAL: To Produce

1. Create an architectury mod with forge and fabric targets
2. Add this in forge:

modImplementation "maven.modrinth:moonlight:forge_1.20-2.9.7"
include("maven.modrinth:moonlight:forge_1.20-2.9.7")

and this in fabric:

modApi("maven.modrinth:moonlight:fabric_1.20-2.9.7") { exclude group: 'net.fabricmc', module: 'fabric-loader' }
include("maven.modrinth:moonlight:fabric_1.20-2.9.7")

3. Observe that the game launches correctly in fabric, but not in forge

OPTIONAL: Which mods are affected?

Development mod

I'm also using official mappings, if that helps.
