Gmod wont start up

It keeps saying steamstartup()failed:steamstartup faileld with error 1: failed to make a master pipe connection lock. Anyone know a soulution

Did you try restarting your PC? most of the time this error gets fixed by that.

If it doesn’t, shut down steam, remove clientregistery.blob from the steam folder and start steam.

Thanks bro
