If you actually read or paid attention you would’ve noticed that the screen only shows up once unless you change this specific registry value: Computer\HKEY_CURRENT_USER\Software\Basically Games\Baldi’s Basics Classic Remastered and changed the DWORD value starting with DxDiag_result to 0 (or really anything other than 1)
The screen is only meant to show up once, the actual way to tell is to try it out. Otherwise, the mod may be conflicting with another one, and for that, just get rid of any other ones. I recommend Key Cheats or Fasguy’s Mod Menu way more than this tbh. Hope that helps :)
