The problem has already been described as a bug:
However, using Unity 2020.3.26f1 I would assume that the problem is solved or someone knows a hack?
Weirdly the bug persists even after reinstalling Unity entirely … maybe there are some cached files that remain when I deinstall Unity via Unity-Hub!?
Update
I even got the same problem after installing a completly new version of Unity. Very strage… Does anyone know where Unity of Unity-Hub keeps cached files of the adb debugger (the text i put in the filter) so I can delete them?
Anyway: Does anybody know a quick fix, how to get my Unity working with adb again?
