Windows doesn't boot (stuck on spinning wheel), "Deleting snapshot"

Hello, I have Parallels Desktop Version 14.1.3 (45485) for Mac (macOS Mojave 10.14.6) and run Windows 10 on it. Whenever I launch Parallels and Windows, it gets stuck with the screen attached (spinning wheel), saying that it is deleting the snapshot - but it does that for eternity and Windows doesn't boot. Most menu items are not selectable (grey) - in particular those related to snapshots. How can I get Windows running again? Thanks very much for your help!
PS: I sent Parallels the technical report No. 358619812.
