Error opening InDesign and Illustrator 2021 on macOS Catalina

Unfortuantely I can not use InDesign Version 16.0 on my mac. 😞

To get sure that it has nothing to do with Mohave, I just updated my mac (from the end of 2015) to Catalina 10.15.7 and de- and reinstalled every adobe product. But still, when I would like to open InDesign, there is an error-message and the opening-process is interrupted. My colleague, who has the same mac (same year, same updates) doesn't have any problems. When I use InDesign version 15.1.2 everything's fine.

The same problem comes with Illustrator, but here, it just closes directly after opening (without any message or information).

Photoshop works.
