Environment

• MixinBootstrap version: 1.0.3
• Forge version: I am using the Forge 1.15.2 from Tlauncher
• Minecraft version: 1.15.2

Issue Description
When I start the Game it crashes. When I remove the MixinBootstrap it works like always, but I am not sure if it is MixinBootstrap error or maybe Lithium. I don't know if another mod could be crashing my game.
I was using Forge 31.2.20 before, but now I want to use the Forge 1.15.2 because I need this version to create a server with my friends on tlauncher.
