The same crash happened last night using the iso file from 15 Nov 2021 on a different computer.
I will try again later with today's daily iso.

Same problem with the daily downloaded today 16 Nov 2021.

Problem still seen in the iso file of Xubuntu 22.04 downloaded this morning.
Live session is still running well but installer crashes very soon after starting.

Unlike today's Ubuntu iso, 2021-11-24 08:32, today's Xubuntu iso times at 02:14 is still crashing.
I assumed all the diffeent DE versions would be fixed at the same time but apparently not; maybe tomorrow?
I'll zsync and try again if I have time.
