it must have gotten deleted by either you or your antivirus. Turn off your antivirus or make an exception for the MelonLoader folder, then reinstall it.

Im having the same issue. Fresh install, no antivirus. The game is a 64bit game which uses IL2CPP.

I had same issue when installed with automatic melon loader. Then uninstalled and installed manually. Instruction can be found here: https://github.com/LavaGang/MelonLoader/blob/master/README.md
