Hi !

I got a crash on 1.21.1 version when open save in single player

Game loading without issue.
I use Forge client in 1.21.1, I tried with just MaFgLib.
Here is the issue report :
The game crashed: mouseclicked event handler
Error: java.lang.NoClassDefFoundError: net/fabricmc/loader/api/FabricLoader

Any idea for solve this issue ?
