BalenaEtcher has the same result (after the initial boot and setup, hangs on the Volumio screen). In the mean time I’ve flashed a new image of RPi 32-bit using the RPi Imager. Booted the Pi and got to the desktop no problem. The keyboard works as expected (no double keystrokes) and I can get to the terminal window and run fdisk as a sudo. It’s not what I want of coarse as I’m trying to build a music server but it has confirmed the keyboard problem is something to do with Voumio OS.
Looking at this other post it seems like the same issue with reboot?
