  • This API is not supported for this application type - Api=_Get. Module=__internal.dll. File=Assembly-CSharp-firstpass.dll.
  • This API is not supported for this application type - Api=_Set. Module=__internal.dll. File=Assembly-CSharp-firstpass.dll.

Are you using Master configuration?

Check you scripts for __internal BTW, possibly caused by those.
