Just tried booting 9.1.001 but it's not going well for me. Kodi starts up, but crashes right after it's detected the CEC. Sometime it shows the wizard, sometimes it already hangs before then. I've tried multiple usb-c power supplies, multiple cables, and multiple SD cards.
On a hunch I tried the other HDMI port today, and it's booting into kodi properly now. In case it's useful to anyone I'm using the port closest to the power supply port.
