Safely Diagnose PC Game Mod Problems

Find safe reversal steps when a game fails to launch or crashes after adding mods or installing an update.

FIRST CHECK

Start with these checks

  1. Close the game, copy the saves and record which mods you installed.
  2. Disable mods using the correct manager, manual-install or Workshop procedure. Move only files you can confirm you added yourself.
  3. First test the unmodified game only as far as the title screen. Do not load and overwrite an existing mod-dependent save. Verify base files only if corruption is suspected.

Try one change at a time and undo it if it does not help. Follow the game’s specific official instructions where they differ.
