Diablo 4 Error on Launch

When I try to launch diablo 4 it gives me an error saying “Failed to create index Mutex” and it only gives me the option to exit or ignore which both close the window and do nothing. I have uninstalled and reinstalled the game and still have this issue. Any advice?

This is the Bnet for PC forum. You’ll want to search and maybe post in the Diablo IV forum for issues with that title.
