I’m having the very same problem and was about to create a similar topic [sinse for some reason I don’t have permission to use the “Search” section on this forum].
I already tried:
- Disable Steam Overlay;
- Start up Garry’s Mod from a fresh reboot;
- Check game cache integrity on Steam;
- Disable all Extensions;
- Delete the garrysmod folder from my Steam ID folder;
- Update my graphics card driver to the latest version from the manufacturer site.
I’ve sucessfully joined a Garry’s Mod multiplayer game about a month ago, then I stopped playing for a while and now this…
As Bender said, the problem only happens on Multiplayer games, either I’m creating a server (both LAN or Internet) or joining an existing one.
The exact error I get is:
**The instruction at “0x16ac3571” referenced memory at “0x0f7edfe4”, The memory could not be “read”. Click on OK to terminate that program.
I have a couple crash dumps, but I’m not sure if I should post this sort of stuff here.

“vgui_allowhtml 0” seemed to fix the problem, at start. But suddently I got the very same crash again minutes later. Is there any other solution to this problem?
