Please tell me what's wrong and do it in stupid person language cause I have no clue what any of this means. I could access the maps  before and yes I do have a good enough cpu. This is an issue with forge and not vanilla minecraft.

This isn't true this is something wrong with pixelmon either you have configured something wrong or it's a bug and needs to be alerted to them. I can't diagnose it entirely because pixelmon is not open source and all I can tell you is that they are trying to generate a random number with an incorrect parameter.

Sorry, I meant its an issue with Pixelmon on forge, The  crash did occur when i was editing the config for Pixelmon. I assumed this was the reason but I have no way of changing it. Wait, maybe i do hold on i think i might be big brain

Thanks a lot, I realized that if i reset to default settings in the game start screen i could fix it without needing to be ingame. Appreciate it.

You should still report that to the pixelmon devs. Because you being allowed to get that error is a bug and should be fixed.
