For anyone coming in later, that is running into similar problems with the apple silicone dmg installation and the desktop client working. i had to both (a) exclude all Docker items in System Settings (Login Items & Extensions → Exclude all items with ‘Docker’ from Allow in Background and (b) kill all Docker ops running via the Activity Monitor (CMD+F Docker → CMD+A) → kill all. Then I opened the desktop client again and the window popped up.
