SOLVED No Sprites and Backgrounds Appearing (Maybe Firewall Problem)

I'm having a problem with sprites and backgrounds not appearing in any room and was told is was likely a firewall thing in an antivirus. I have Avast. What settings should I change to allow GMS2 to work properly?
Have you tried cleaning your project cache by pressing the broom icon button? Have you also tried resaving the project under a different name? Or maybe try importing the project instead of opening it.
