Issue with adding new device

Hello @infobeamer-fw
Here I am wondering if Murphy has a special affinity for giving me the most ill timed errors.
Tried to add a new device as usual, and lo and behold, this error showed on my screen

It shows that the device runs the latest bootloader and it should run, business as usual. But it won’t.
Tried the stable and testing image, no dice.
Ideas?

It seems when the Pi tried to boot from the SD card, it not cannot read from the SD card. It seems this is the exact same issue also mentioned here or here.

Can you try a different SD card and check if the SD card reader isn’t dirty in any way?
