These possibilities may or may not be of value in your situation; however, it beats waiting for the reBoot process.

You Win 10 v1909 2020-03 would be the latest which if on a metered/measured internet connection may not have actually been downloaded/installed.

At the command prompt as administrator:  sfc  /SCANNOW

If you do not have administrator permissions:  WindowsExplorer->rightClick DriveWhereProSeriesLocated->Properties->Tools TAB->click CHECK Button for the option that will check the drive for file system errors.

The other CHECK Button is for optimizing the drive.  This might be very useful if the drive for INTUIT ProSeries is highly fragmented.

Be patient.  These commands take forEVER to complete sometimes.

If you notice any system messages/alerts that may just instantly appear then disappear try to remember to the best of your ability what it was and inter this information in the "search" box of your favorite search engine.  The information you receive may be impossible to decipher though it might give ProSeries Tech Supt (level 2) at least enough information that they might be able to diagnose and provide a viable solution?

Note:  At the command prompt  sfc  /? (as administrator will give you some cryptic help that is typical of most software).
