Can't Close Garry's Mod Properly

Hey, I’ve just noticed that whenever I try to properly exit Garry’s Mod, the window just freezes up and I have to end the hl2.exe task to make my Garry’s Mod window close. Is this happening to anyone else or is it just me?

Edit
Nevermind, works now.

I have a similar problem, except for some reason I can’t open up the task manager. I just Ctrl+Alt+Delete and end the task before hitting “Quit”

I have the exact same problem. I have to close it using task manager.
