I have recently purchased a new HP computer with Windows 10 and installed my standard office software including DropBox (v53.4.67). As soon as I installed DropBox, and started to do work I experiencedproblems with File Explorer. When I clicked on File Explorer on the Task Bar, File Explorer opened without showing any folders or files and displayed "Working on it." File Explorer hangs and the only solution is to close the window. My work around was to right click on File Explorer and get to File Explorer without going to Quick Access. If you click on Quick Access - File Explorer hangs. The only way to get File Explorer to work is to go to Quick Access Options and clear File Explorer history. Through trial and error, I discovered I can keep DropBox working and File Explorer, but I have to deselect the "Show recently used files in Quick access."
About a month ago I bought a Dell desktop and installed DropBox and had the same problem. (One of the reasons I returned the Dell was I thought the computer was this File Explorer problem.) Since I am having this same problem with a brand new HP, this is clearly a reoccurring problem with DropBox. I have used DropBox at work for years and never had a problem. I never had this problem with my old computer, so it seems to be something related to a new computer and a new install of DropBox. Any help or suggestions would be appreciated. I can live with arrangements, but would prefer to have the convenience that Quick Access provides. Thanks.
