What are these icons and how do I get rid of them?

When I first launch unity at the beginning of the day, these two icons will show in the bottom-right corner of all my tabs. I also can’t double-click on any of my hierarchy or asset folders. After 10-20 times of closing and re-opening Unity, they eventually go away. It seems pretty luck-based to be honest.
