Gmod Freeze at Start up screen and Not Responding

Howdy, I got a problem about Gmod. The starting up screen is freeze after the Facepunch logo. its goes light blue screen and not responding.
I searched up on “Help & Support” and found out im not the only guy who got this problem.
I tried to delete all of my addons and Reinstall gmod…but still doesn’t work.
Is there anyways to fix this problem ?

( Sorry for my bad english )
