Trying to open menus freezes program

I am running version x64. I am unable to open any of the menus (Options, Collections, Hotkeys, Show Credits, or View Intro). Whenever I try to, the game Dims and freezes. At this point all I can do is hard shutdown the program.
Is there a fix to this or what??

This may be your antivirus software blocking the Blizzard Browser.exe from running (which is the web browser we use to do these UI screens). You may need to add this as an exclusion to your antivirus software.

Can you say which software (incl version) you’re using and we’ll try to reproduce it internally?
