Forge v14.23.4.2750-1.12.2

I get this crash on game launch.
Here's the crash report.

What exactly did you do? Sorry for not responding earlier! Any other mods? Do you have a cracked account? Did you not set the game language?

What is editing your language?

It's definitely not a cracked account. I think it was a either a bad forge or minecraft launcher version, because after updating forge, I didn't get the crash again. I'm using version 14.23.4.2757 now.

Hmm ok!
