Strange singleplayer problem

Good evening, I got this strange problem with starting singleplayer games now.

When I start a new singleplayer game everything loads perfectly, until the last loading thing comes GMod just freezes. Tried reinstalling gmod 2 times now, and I’m wondering if you have seen anything like this before (fix for it) ?

Multiplayer works perfectly and I get none errors.

Picture.

This is similar to what I’ve been experiencing.

I don’t have a solution either.

The problem is that when you click the game window during loading, Windows thinks that you want to provide input to it, but it’s busy loading. Windows sees this an error. Try loading the game but don’t click the window during loading.

I know sir, I clicked to early when I was going to take a pic. Problem ia that it just freezes ar the last stage, always worked before.
