Same problem.
Looking in task manager, I can see it as a "background task" but not an application.
Called support. First guy told my - restart your computer. I told him I've already done that. So then he said to just wait and try it again tomorrow. !!?? I said no - I've had the issue for multiple days. After many basic questions, got forwarded to someone else. He said others have issue and he'll have to call me back tomorrow. I'll wait and see I guess.
