SDL Trados Studio 2021 crashing

Since upgrading to SDL Trados Studio 2021 about two weeks ago (currently running 16.0.1.2917), the entire application has been crashing regularly (at least once a day) while working in the editor. There is no error message; the application window simply closes. I can then restart the app and continue working. Is this a known problem, and is there a fix? (I am running the app under Microsoft Windows 10 Home, version 10.0.19041 on an Intel Core i5-6600 CPU).
