I Have NO idea what happened, i did nothing different then the usual, but it just stopped working , as soon as i start it, it freezes and stops responding in the processes. I’ve tried deleting the addons, verifying the cache, defragmenting, None of those worked. Pl0x help.
Try renaming your garrysmod folder (steam/steamapps/<steamname>/garrysmod) to garrysmodold then try starting up Garry’s Mod.
Also, if you have not already tried it. Restart your computer.
