It was working. Then I was using replay mod and fabric mod to edit footage, I got insufficient memory errors a few times, so I edited the launcher file for fabric to have 4gigs of memory. Same error. The error file says something about sheep entity's. So I edited the launcher file for fabric mod too 8gigs of memory. Then it instantly crashed from the launcher with error code -0 and now no launcher opens at all.

I'm on my phone for putting in this report, so I'll log in with my PC and try adding the crash logs and stuff after I send this
