I'm troubleshooting some mods that I want for a single player world in 1.21.4 and I was having trouble with a resource library config crashing my game so I tried another mod and the library config for that was causing crashes as well. I've updated java and forge recently. Both of these dependency mods have caused Exit Code: -1 but I'm using the crash report for the mod that I was originally wanting to use.
