Problem installing ubuntu 22.04

I used the tutorial
DLed ubuntu-22.04.1-desktop-amd64.iso
Used Rufus to write a GPT partition with the iso on a 32 MB USB Key

Install using normal resolution starts, but never ends…

Low resolution install starts, and goes to the end, but when the RockPi boots, the desktop appears for 1/10 second, with mouse moving I think, then black screen and RockPI is crashed. (Not sure if it evens reboot.

What am I doing wrong(If I am) ? Should I install 20.04 ? (not 22.04)
The RockPi is a 32gb, hdmi version
I’m not a linux specialist. But a decent technician.

Can someone confirm having installed 22.04 lastly ?
