Crash at launcher issue

March 28, 2025Mar 28

I made a custom pack, but i can't even load it, it just crashes at launcher, giving me Error 1. I looked at the log, and it just doesn't seem to tell me what the issue actually is. Here's the report.

Edit- Trying to get report, but copy paste being weird
