Fresh RatOS can't connect to WiFi or Ethernet

I reflashed the SD card with the newest RatOS as the old one was making problems.

Downloaded Balena and successfully flashed the SD card. I inserted it into the Pi 4 and powered the board, but no WiFi came live, waited 15 min, and kept checking both on my phone and desktop..

I tried the Pi powered in the power outlet disconnected from the printer, and also connected to the printer + power.

Then I plugged the Ethernet cable, this is how I used the printer before, and still could not connect.

Later I downloaded Notepad++ and added the SSID and password, saved the file as wpa_supplicant.conf, inserted it back, and restarted, still could not access via http://RatOS.local/ or

What can I do? please help.
