Unable to spawn props and no-clip on sandbox.

I have no clip enabled and I do not have a prop limit.
Basically title says all.

Do you get some error or some message when you try to spawn a prop?

None at all, I just cant spawn PHYSICS props. Effects and ragdolls are fine. But I cant pick them up with the physgun.

The first thing you could start with is going to C:\program files\steam\steamapps\your steam name\garrysmod and then renaming the garrysmod folder there to “garrysmod old”. This will get you a fresh start, and if the problem is fixed, some addon is breaking it.
