1.18.1 MultiMC Launcher Crash

[Omega]

When I try to launch the instance the Minecraft window will pop up for a second then the instance will crash. The log seems to think I am missing some files I guess. I am not sure how I can fix that.

Solved by deleting libraries/me and reinstalling

Yep. It was due to OptiFine jar being missing from the mods folder.
