This message happens when you've got multiple Intuit Products open (I think the automatic background updates have something to do with this), or you've got an anti-virus or cloud backup that's scanning your Intuit files, I think it may also happen if your internet connection is unstable.

Ive blocked Proseries files out of my anti virus, and only let my cloud backup run after hours, I do have a crappy internet connection, so it does still happen to me now and then, but it was really bad when my cloud backup was running, scanning PS data files.

I am running Win 11, but it used to happen back when I had Win 10 too.
