reopening recent files doesn't work

[David5D14]

When reopening Acrobat (V 24.1 in Windows 10), it doesn't offer to reopen recent files and when I ask it to, I get this error: "There was an error opening this document. This file cannot be found." The files do appear (I just changed the "Documents in recently used list" setting from 10 to 20, but that didnt have any impact) and can be opened, though, by going to View all recent files and reopening each from there.

Are these files stored in a cloud service (e.g. DropBox, OneDrive, ...)? If so, the problem may be with the integration with that service. 

Does not make ia difference if you are in the new vs. old Acrobat user interface?

Thanks Karl. The files are local, not in the cloud. I hadn't thought about the interface, though. I just reverted to the old one (which I think I like better anyway!). On one test just now, it did reopen the doc I had had open, though it didn't prompt me like it used to. I'l have to give it a few more tests over the next couple of days.

Additional info - after switching to the old interface, Reopen PDFs is sometimes grayed out and other times, wif it is available, I get an error for each document.
