I had a problem with Deepl on my friend's Intel Mac when updating Ventura. He had installed the app some time ago there and it seemed corrupted in 13.3 and could not be opened afterwards. Uninstalling apparently didn't help. The message kept coming up that the application was corrupted and should be sent to the trash. In the end, I used EasyFind to remove all rests in visible and invisible folders and succeeded afterwards on reinstalling it after which it worked without problems.
