Trying to use optifine for minecraft 1.19 isn't going to work well with minecraft 1.20.1

Check their download page for their latest preview tested against forge 47.1.43

Issues/questions about optifine need to be reported to them.

Thank you! I indeed tried installing Optifine a while ago before I had Forge, but I thought I deleted it. And now it appears there where indeed some files left. I deleted them and now it's starting up again!
