Have not seen that error code before, What happend if you run the command again? Even now you have emptyed the folder. However if it does work a second attempt, i might have an idea where the issue originates from.

I ran it multiple times with the same result. Even now with the InFlight folder completely empty.

On her PC there's an "admin" user so I tried that, and it still fails. So logged back on to her account and tried once more, and it worked!

Ok that somehow confirms my suspicion why it happens, but not sure of the solutions. Or why it happens. I think the handle gets invalid because process is not yet created, or already ended. And so not able to get the handle. Are the machines that failed, older machines, or really slow/heavy load?

Have done the test with Highest UAC and the removal of administrators from secpol.msc. And it still worked at my end. So people don't have to test that anymore.

edit: New script with some more debug info.

There's 4 systems in our household - mine and the wife's desktops are both Intel 10th generation based sysrtems, so fully W11-compliant (and configured as such). Other 2 are an older 8th generation desktop and a 14th generation Dell laptop. All are running Windows Home 24H2. The only failure was on the wife's desktop. Happened a couple of times with two different accounts, but then worked. The others all worked first time. The desktops deleted 190,000, 90,000 and 85,000 directories and the laptop 15,000.
