Every Time i try to load a modpack that a few friends of mine play, the loader fails to load some mods and spews out an error.
The game works without any mods and the mods it fails to load are different each time which is why i'm posting it here.
This exact set of mods works perfectly fine on both a server and my friends clients who are not getting any errors at all (I know it's the exact same because i sent them the .jars).

Things i tried so far:

• Create new launcher profile in different folder
• Completely reinstall Forge, Minecraft and the Minecraft Launcher. Sometimes this made it load exactly once before going back to the errors but it's a bit of a luck thing it seems.
• Restart PC

I'm at my wits end here so any help is appreciated

Many of your mod file names suggest you didn't get the mods from their original sources. Check out https://stopmodreposts.org/ for why this is a problem and then obtain your mods properly before doing anything else.

Fair point. Got all the mods from CurseForge now (is that the correct one?) but the problem is still the same, so i still need help.

Looking through the crash reports, it always seems to be a ClassNotFoundException, but always on different mods and when i look inside the .jar the class is definitely always there.

Looks to be an issue with GeckoLib. Make sure you follow the installation instructions.

The only installation instructions for that mod on their page are very clearly directed towards modders intending to make use of the library so i don't see what i could have done wrong there. Re-downloading it didn't work either.

Little final update: I tested through all my mods and the problem was the "Thatched villages" mod which for some reason only caused issues for me.
