I’m running Ubuntu 21.04, and recently updated my machine, then rebooted. Now I can’t launch any snaps at all. null is the simplest snap, and won’t launch, but the same happens for every snap I test.
alan@robot:~$ null need to run as root or suid

I have proposed enabled, which I did because I believe I need 5.10 kernel because a bug in 5.8 makes my nvme go read only periodically.
Something may have come down from proposed on hirsute which messed my machine? I don’t know.
alan@robot:~$ snap version snap 2.49+21.04 snapd 2.49+21.04 series 16 ubuntu 21.04 kernel 5.10.0-14-generic
Any ideas what I can do to debug/fix this? My machine is pretty useless right now.
