error: system does not fully support snapd: cannot mount squashfs image using "squashfs": mount:
       /tmp/sanity-mountpoint-913738666: mount failed: Operation not permitted.

This looks odd, snapd should know to use snapfuse in such environments.

Can you show "lxc config show --expanded" of such a container if you're still hitting this issue?
