Dropbox app on Windows 11 intermittently hangs.

Had another hang overnight and none of the photos I took this morning uploaded until after I killed and restarted Dropbox.  My computer was very busy overnight with a new local backup (transferred 12GB in files over USB v3.2).  Before I killed the process tree, I took a screen shot in the task manager and found that the process was suspended (see image). I could not get the processes to resume by clicking on the stop icon, nor by right-clicking on the individual processes.

I think that might be an interesting data point. I can't imagine that Dropbox would have been doing anything overnight in the background.  The only other processes that were suspended in a similar way was the "Windows Shell Experience Host" and "Windows Default Lock Screen".   

I don't remember seeing this the other times that I had to kill and restart Dropbox, but maybe this is something added with Windows 11 24H2, which I recently installed.

Before I killed the processes, I opened the Dropbox folder. All folders were fine and speedy except the "Camera Uploads" folder, which refused to open in Windows Explorer. It was empty and Windows spun trying to display it.  Restarting Dropbox fixed it.

I doubt any of this is enough to find a solution, so I'll keep monitoring. However, it may be related to my computer getting really busy overnight, running backups.
