White Screen When Spawned

[Baguette]

So when I choose my character and spawn, game turns white.
I can see shadowplay FPS counter and I can press ESC for Garry's Mod Main Menu, but I can't open the HL2RP Menu with tab.

Things I tried:
Deleting and only installing content addons
Re-installing Game
Verifying integrity of game files

What else can it be?

Does this happen only when joining one of the servers or does it persist anywhere else?

Only at HL2RP server.

EDIT: I managed to get it working my restarting my router, problem wasn't in my router properly so it fixed itself I guess...
