File History Clean-up post 20H2

Question

I am having a problem with file history. If I go to advanced settings and click on Clean-up versions no matter what term I enter, including 'all but the latest one', I get a message:- Could not clean-up File History - Element not found.
I am using a NAS share mapped as a drive letter as the destination for the File History.
The mapped drive responds to the file explorer, displaying the contents of the File History correctly as far as I can tell.
I have seen a previous question about this problem which is now closed, In which there is a reference to repairing the the O/S but refers to a specific KB patch which refers to a build version prior to 20H2 which is what I have updated to.
Can I assume that that patch is embedded in the 20H2 version of Windows 10 Pro?
Is there any easy way to resolve the problem?

Hi,

Yes.
I suggest you download the media creation tool & double-click it to run, then choose to upgrade this PC now.

Open a command prompt and run

FhManagew.exe -cleanup 90 (90 would indicate to delete backups older than 90 days old)
or
FhManagew.exe -cleanup 90 -quiet

If you specify "0" that would mean to delete all but the most recent backup.
