Character dissapers and image gets blurry

After playing OW for a while my game gets blurred, my hero dissapers, and i dont hear sound effects. Also i cant go to the menu pressing ESC key. What is this?

Hi,

This is not the Overwatch forum.

This forum is for technical support on the Classic (ie, legacy) Games such as Diablo II (2000).

Overwatch has its own forum here:

Best of luck with this.
