Containers not starting due to shifts on Ubuntu 20.04 HWE kernel

Ubuntu 20.04. During snap LXD 5.21 update, containers stopped working due to Required tool ‘zpool’ is missing.
I installed the HWE kernel but now I have a problem with shiftfs
Error: Failed to setup device mount "home": idmapping abilities are required but aren't supported on system.
1.Is it safe to switch security.shifted=true or false for storage volume without any consequences?
2.Can I switch the security.privileged=true or false options for the container without any consequences? Until this problem is solved, this is probably the only option
Unfortunately, updating to 22.04 is not possible and I don’t know if it will solve the problems.
