Forge version: 47.2.0
Minecraft version: 1.20.1
Mod version: 4.0.0

For me, the game gives an Error 1 and crashes before it even generates a log. However, two people have been able to provide these logs on Curseforge:

Fixed

Same Problem here, just use one version before the new one and you wont crash for now
