Crashing after a few minutes in-game.

I’ve been crashing like this quite often. I have done all the typical fixes for crashes, but it hasn’t worked. Completely deleted Gmod, unsubscribed to all addons. Only play on one server, so I only have the addons for that server. I get 7-8 files validated when I verify game cache, after each crash.

At times, I can play for hours without crashing, but when I crash, it won’t stop crashing. I’m assuming this is due to something on the server.

The crashes are all similar to the one above, from what I can tell.

Are you using tf2 models/proops/etc on server or while playing?
