Windows 10: Windows 11: Error message "The parameter is incorrect." when trying to add files to...

Hi,I'm running Microsoft 365 and recently I used Norton Utilities Ultimate to improve my laptop's performance, e.g. it does so by cleaning "system junk" and optimising system processes.It seems that after Norton's system optimisation, my "favourites" were removed from File Explorer. When trying to re-add these files by right-clicking on the file in File Explorer and selecting "Add to Favourites" I get the following error message: "[file path] The parameter is incorrect."Proposed solutions I already tried without success:1 Run DISM toolISM /Online /Cleanup-Image /ScanHealth DISM /Online /

parameter is incorrect

On Windows 10 when I try to create a list of all files of a particular type, I get this message during the search: "The parameter is incorrect."

I have run chkdsk and sfc and find no problems. It happens more frequently when the drive being searched is an external USB drive, but also happens on the local disk. There is no explanation of *what* parameter is incorrect.

Creation of the list (a txt file) completes, with no appearance of the error messge... but I don't know if all files were found or not. Typically, this message is given when I search for a filetype of which I know there are more than 100... with the rate being
about twice per hundred files.
Example of the searches:

dir *.css /S>_allCSS.txt

dir *.html /S>_allHTML.txt
Over the weekend I tried this on 14 different systems, with different external drives. Same result. Oddly (maybe?), no such message is given when running the search on a NAS drive (tried 2 different ones), but the search takes considerably longer on the
NAS drives.

Does anybody know what causes this bizarre detail-free error message?

Any assistance greatly appreciated!
