Describe the Bug

Today I was about to play some minecraft on a 1.16.5 multiplayer server, after I joined it said "Internal Server Error", after some troubleshooting, create mod was the one causing it even though it was fine the day before. I've tried re-downloading it and even downloading different versions of that specific version but nothing worked. It works fine on a single player server but for multiplayer it's not. I know the server isn't the problem because all my friend's on that server have been getting on just fined. ONly one of them had the problem too but fixed it by downloading curse forge, but that didn't work for me too.

Reproduction Steps

1. Opening Minecraft
   2.Joining Multiplayer Server with create
2. After loading a bit, "Internal Server Error" pops up

Expected Result

I expected to just join the multiplayer server like usual
