What’s your graphics card?

Did you try restarting steam/your computer?

Looks like kind of same problem?

Doesent look like the same problem. I have the same problem, when i try to start steam i just get “Preparing to launch Garrys Mod” and then it just closes and nothing happens. I have tried to restart my pc and steam, nothing works.
