Describe the issue.

Hello,
I'm almost sure this error is caused by a space in the game path.

In my opinion you should change code in line 53 of:
"MelonLoader/Dependencies/Il2CppAssemblyGenerator/Packages/Models
/ExecutablePackage.cs"

from:
processStartInfo = new ProcessStartInfo(ExeFilePath, parenthesize_args

to something like:
processStartInfo = new ProcessStartInfo("\""+ExeFilePath+"\"", parenthesize_args

I'm right?
