As far as I can tell from the logs, the problem actually affected h2static and lxd snap, and no other snaps, right?
Do you see any snap changes about h2static snap that failed? If so, can you show its tasks as well ('snap tasks ...')?
Did you try to remove (with 'snap remove') any of the affected snaps before experiencing this issue? There was a problem with remove hook of lxd snap fixed 2-3 weeks ago which - combined with https://bugs.launchpad.net/snapd/+bug/1899614 - could leave if in a broken state after failed snap remove.
