To start with, I'm using the desktop version on a MacBook Pro, on Windows via Parallels software.
Problems after updating to SDL Trados Studio 2021 SR1 - 16.1.3.4096:
I'm repeatedly (but not always) receiving the following error message when launching a file for translation or review.

Everytime I start working after this error message, there are parts of the interface that don't work properly, e.g.
- the "complete review "button is not present
- unable to confirm a change in a translation (choice not present after right click and no change of confirmation status after confirming with shortcut. Yet when closing, saving and reopening, all changes have been taken into account.
