Gmod crashes nearly on start up.

When I start gmod, it crashes 2 minutes on start up. It doesn’t have a message. Gmod just disappears from the toolbar.

Here’s the latest crashdump - http://dumps.metastruct.uk.to/dumper.py?dump=hl2_130620_crash_2013_6_30T1_52_24C0.mdmp

Found your issue.

  1. Why is Steam on your desktop?
  2. Go to /steamapps/(usernames) and delete (or drag somewhere) your Garry’s Mod folder there. Then, delete local content for Garry’s Mod in Steam and resinstall.
