I am seeing possibly the same crash using xubuntu-24.04-desktop-amd64.iso, the installer crashes at seemingly random times with the same error message as above:

[xcb] Unknown sequence number while processing queue

[xcb] Aborting, sorry about that.
ubuntu_bootstrap: ../../src/xcb_io.c:278: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.
Aborted (core dumped)

I've observed it all four times I've tried to run it so far from the Xubuntu Live session, first time was just after the keyboard layout selection (wasn't running in terminal so didn't see error message on this one), last three times were on the partition selection (under Manual Installation).

This gives an error message "The problem cannot be reported: ubuntu-desktop-bootstrap is provided by a snap published by canonical. No contact address has been provided; visit the forum at https://forum.snapcraft.io/ for help."

I do have my /var/log/installer archive and `journalctl > journal.txt` from earlier in this live session though (IIRC after three crashes). Note that none of these files appear to include the xcb error message.

I saw that there's an updated `ubuntu-desktop-bootstrap` snap on the candidate channel, I tried using that and I got a possibly different crash the first time (didn't see any error message, it just exited), but the second time I saw the same xcb error as above.

I'll try rebooting and selecting safe graphics to see if that helps.
