You have some 3rd party D3D modification interfering.

I dont know where to find those R1CH but I kinda found something with mumble. When i uninstall mumble it works but when i install it back and use it after I Got csgo on my preview it turns black. I dont have anything on my cs no mods or anything just vanilla csgo for competitive wise.

Turn off the mumble overlay feature.
