I installed the recommended version of forge 1.12.2.
If i remove blockbuster minecraft works fine.
It's not a incompatible mod because when I run minecraft with only: blockbuster 1.6.5, mclib 1.4 and metamorph I have the same problem.

i'm literally stupid 😂

That’s clearly not a recommended version 😂

Well, install recommended and have fun! 😉

I mean, it’s literally saying what to do. 😅

Remove Blockbuster and screenshot the main menu screen fully (or just the left bottom corner).
