Thanks for reporting. Can you send me the output of snap --version and lsb_release -a? Censor any information you're not comfortable sharing, of course. In the mean time, you can just try any other package. Since this seems to be a confinement issue, that should normally just work.

A little googling turned up that cgroups v2 should be supported in snapd 2.46 (see snapcore/snapd#7825, https://forum.snapcraft.io/t/fedora-32-cgroup-v2-is-not-fully-supported-yet/19295/4). Maybe there instructions will help you update your snap installation.

Alright, so upgrading snap / snapd to 2.46 or above should help you
