Catalina 10.15.1: problems opening files, multiple applications

Since upgrading to Catalina on my Macbook Air (2015) I have had occasional problems opening files in multiple applications, including (so far) Preview, Keynote, MS Word, Scrivener, and others. When trying to open a file, I get the simple message "The file [X] could not be opened", with no further information. There do not seem to be permissions problems with the files themselves.

Rebooting the computer seems to resolve the problem, but then within a couple of days it crops up again. Has anyone had a similar issue, and is there a solution?

Thanks.

MacBook Air 13", OS X 10.11

Please determine if the same problems occur in "Safe Mode": Use safe mode to isolate issues with your Mac .

Needless to say, if you are using any non-Apple "anti-virus", "cleaning", or "Internet security" junk, anything at all in that broad category of useless garbage, don't. A lot of things won't work if you do.

Problem possibly solved after an online chat with Apple. Resetting permissions in the Home folder seems to have resolved the issue.

Same thing started happening on my iMac 2017 recently (after Catalina upgrade). I can't open ANY file, weather from inside an app or double-click/right click open with... All is fine after a reboot, then after a while it starts again.

Workaround I've discovered... I have no problems opening files in "Downloads" folder, go figure. So I copy (since I can't even move) a file to Downloads folder and then open with a double-click. This is concerning, I initially suspected my "Fusion Drive", but if it was a hardware issue, it wouldn't open fresh after a reboot either, right?

This may or may not be relevant, but recently I've also noticed there are times where my Microsoft Office applications in particular (Word, Excel) simply will not open files. You double-click them from Finder, or select them from the Office menu, and literally nothing happens. Here too, a reboot solves the problem. Hard to tell if it's related.

The problem recurred for me after about a week after I followed the repairing permissions procedure. I ran the procedure again today and it seems to have cleared it up. No idea why the problem keeps recurring, though.

Booting into safe mode does resolve the problem (as does *any* reboot of the machine). Logging in and out my user account does not have an effect, though.

Successfully reset home folder permissions and ran terminal command.

This did NOT resolve the problem for me.
