Can not install Sonarr

Sonarr version (exact version): Newest
Mono version (if Sonarr is not running on Windows):
OS: macOS Catalina
Debug logs:
Description of issue: I simply can not install Sonarr on my iMac. I download it from the web site, move the file to Application folder and try to start. Only to get a pop up saying that the program Sonarr kan not be opened.

Does anyone have an idea what to do to fix this?

Thank you in advance

Same issue here. I have a completely fresh install of Catalina 10.15.3 and I’m getting the same thing.
