Gmod crashes randomly while playing TTT

When I join a ttt server, I can play for some time, from 5 minutes to around 2 hours, and then gmod will crash out of the blue.
I’ve tried verifying cache, reinstalling, uninstalling all addons, removing downloads, still doesn’t help.
Here is my crash dump:

Hope you can help.
Thanks in advance


Do you have Multi Core rendering enabled? Try disabling it. That fixed Gmod crashing for me randomly
