New update issues, not too worried about a fix but wondering if anyone else experienced this

[QUIDD60x]

I guess there was a new update and it didn't work for me, i only have the basic stuff installed like optifabric and baritone along with malib and litematica. Deleted the me file like it said, and it still didn't work. I can just reinstall the donor version. I was wondering if other people were having this problem mostly, if there is a better or faster fix aswell that would be nice. Thank you to any help!

I'm not sure what you mean by it didn't work. Can you explain more? What launcher and mc version?

@dyiing im using the default launcher, deleting the me file didn't do anything the error still popped up, i just redownloaded the donor version and everything is back though so no worries. apparently there wasn't an update though?
