Trados Studio 2021 SR2 does not start after updating a plugin and Windows update

Dear support team,

I hope you can help with my issue. Two days ago I updated a plugin and installed a recent Windows update. Now I can't open Trados - the start screen flashes for a millisecond and that's it. There is some kind of error screen as well, but it flashes and then disappears. In Task Manager, Trados is running in the background. I have tried all of the methods mentioned in similar theads and also uninstalled the recent Windows update to no avail. 

Many thanks in advance,

Selga
