Wont Start up Error -Garrysmod

Yesterday my Garrysmod was working just fine and now when i try to open it up through steam it gives me an Error message that i haven’t seen before.

Error - “SteamStartup() failed: SteamStartup(0xf0x0012e584) failed with error1: failed to take master pipe connection lock”

This appears a few seconds after i click “play” for garrysmod.


Nevermind i fixed it.
