I used BALENA and RPi Imager for the SD card

1. You must use the RPi Imager.
2. You must specify a user + password in the imager, before flashing the image to an SD card
3. You can also configure a wireless network before flashing

Failing to fulfill 2. will result in an unusable image. To fulfill 2. you need to be compliant to 1.
3. is optional, but I would recommend it, as it is easier in the imager than it is on the Pi through its AP.
