I updated my openSUSE Tumbleweed to version 20230613 (earlier it was a few days older), rebooted and now none of the snaps start.

All give errors like:
update.go:85: cannot change mount namespace according to change mount (/var/lib/snapd/hostfs/tmp/.X11-unix /tmp/.X11-unix none bind,ro 0 0): permission denied
(tens of these)

and as a final one:
cannot update snap namespace: cannot create writable mimic over "/usr/lib/x86_64-linux-gnu": permission denied
snap-update-ns failed with code 1

Environment:

kernel 6.3.6-1-default
snapd rpm snapd-2.59.5-1.2.x86_64
snapd snap 2.59.4

Not sure of the causing change, at least snaps were working with older 6.3.x kernel. systemd just saw update 253.4 -> 253.5 which could be the one, or if 6.3.x introduced something in for example 6.3.5 or 6.3.6.
