"Configuring Windows 10" message @ every startup

I get this message every time the VM starts. Running latest Parallels on Big Sur, v. 11.2.3. In the window is a horizontal thermometer bar, with "Preparing to configure the virtual machine underneath. Does not save the previous VM window size, but reverts to the small nearly illegible window requiring re-inputting the display settings. After the thermometer is about a third of the way across, the VM starts normally except as above.
Any help is much appreciated.

 

Hello, could you provide us with the screenshot of the issue please?

 

Here is the screenshot.

Thank you, Bill
