No reinstallation possible

With the current image file for the Pi3 + I can no longer do a new installation.
After an update from a v0.111.x to the current version no longer worked, I decided to reinstall it. As usual, I loaded the appropriate image onto the SD card with balenaEtcher and then inserted it into the Pi. Normally, the screen output then appears after a short time, which should be waited for 20 minutes … This screen no longer appears at all. With previous installations this worked without problems. It can’t be because of the SD card … I tested several different ones.

P.S. Now after about half an hour the screen appears that I should wait 20min …

Meanwhile it turned out that there were problems with the latest firmware update for my Fritzbox 6591. Basically, the update seemed to be running, but Homeassistant on Pi didn’t work. I don’t know what it was, but the step back to the previous version resulted in everything working as before…
