The same here. I was trying to install an ili9341 at retropie witout luck, so right now I was attempting to do it with retroarch, but I am not able to boot.

I am working with a raspberry pi zero hw, I could run retropie and recalbox 7.2.2 on it, so i supous that the isue is with the recalbox 9.1 image.

I also tried to install recalbox 9.1 with the Raspberry pi imager and with rufus, with the same result.

Conecting a keyboard the only thing i was able to do was rebooting by pressing ctrl + alt + supr. But it allways ends at the same screen.
