The update did not work. (Rasberry Pi4 + SSD 1Tb … macbook pro)

So I started everything from scratch :

1. erased and formated the SSD
2. formated the miroSD card Fat32 and flashed UmbrelOS on it with BalenaEtcher
3. **Insert the flashed micro‑SD into the Raspberry Pi 4** , attach the SSD (via a USB‑3.0 port), powered it on,
4. waited 5 min for the green light blinking to stop, then connected to umbrel.loccal

it ask to create my username and password,

I then get to the main Desktop picture with an empty screen (no dashboard)
