Singleplayer games stop loading

Garry's Mod general
#1

When I try to start my own singleplayer/multiplayer game, not join a server, it will get to something like loading world and then the screen goes black. Then it goes back to the main menu, I think it has something to do with my addons, but I’ve tried clearing the ones I added, and it still doesn’t work.

Any ideas?

Specs?

Specs probably isn’t it, since it’s been working before.

There was an update recently tho, it really messed gmod up.

Any ideas yet? D:

I’ve had this happen when I had too many addons.
