Failed to get children from device: IDispatch error #7689

Getting error when trying to link with my cell phone:

calibre, version 5.17.0
ERROR: Error: Error communicating with device

C:\r\src\src\calibre\devices\mtp\windows\content_e numeration.cpp:322:Failed to get children from device:[-2147213303] IDispatch error #7689

This used to work just fine. I believe that it started to fail with upgrade to Calibre release 5.17.0 or after sending some books to my wife's kindle. I am not sure which.

Using Widows 10 connecting to a Moto Power G via usb.

Both PC and phone have been rebooted. I have deleted files driveinfo.calibre and metadata.calibre with no effect. Windows Explorer has no problem accessing the device. Once it started to fail installing calibre 3.48 had no effect.

Any Ideas?
