• Minecraft: 1.16.4

Crash 1, 2 and 3

Additional context

I believe that you are missing the core mod, as the "main" argument normally means you are missing something.... in this case, are you leading reborncore too.

Yes reborncore itself is already there in my mods folder.

This error also happens:"java.lang.NoClassDefFoundError: Could not initialize class techreborn.init.TRContent$Machine".

It seems that the error was caused by REI because ever since I've installed the recent version of REI this error has been fixed.
