I noticed this one other time a while back but, worked around it and let it go. It happened again today.
When I open File Explorer, it opens with the Home menu open. If I click the File tab, a drop-down menu opens. BUT, if I click on either the Share or View tab, it freezes, I get the little red circle with a slash through it (no symbol) and Explorer closes. Then all the icons on the Desktop reload.
EDIT: If needed, I just copied this from "OS build Info" ...
