Observed behaviour

Just crashes on start.

Expected behaviour

Normal launch.

Steps to reproduce

1. Download Mods
2. Put them when they need to be
3. [ NOTE: I use PollyMC for so steps 1, 2 are automated ]
4. Run the game (java 19.0.2)
5. Wait a bit
6. Look at your perfectly unreadable and huge log without any understaffing why game crashed.
7. [ If it was becuse I was using mod version 1.20.1 for MC 1.20.2 then its still a bug because it should have shown other error and not the mess I see ]

What forge version are you using nvm i see it, you're using 1.20.2 my guy

So, basically you can't run 1.20.1 on 1.20.2? (Asking it separately because in most cases you can do it if major version matches)

if you can run a mod on a newer version you got lucky but it's not guaranteed

doesn't matter which one
also not crashing does not mean that the mod is actually working correctly
