Proxmox rescue disk trouble

[versus]

I installed a Proxmox 7.3 with a ZFS RAIDZ1 file system. After finishing the installation I upgraded to Proxmox 7.4 with apt dist-upgrade.
Now I am trying to boot with a rescue disk.
I try the proxmox 7.4 rescue disk and when I try to boot I get the error:

Error: Unsuported embedded BP (type=116)
ERROR: unable to find boot disk automatically
Press any key to continue

When try with Proxmox 7.3 rescue disk the error is different

Compression algorithm 111 not supported
 ERROR: unable to find boot disk automatically
Press any key to continue

Is this kind of error normal?
Is Rescue mode really useful for ZFS file type?
Which rescue Linux distribution do you recommend?
I have sometimes tried Ubuntu as a rescue disk but the ZFS it incorporates does not have all the necessary features and the pool is mounted in read-only mode.

I boot the latest PVE ISO, then start the PVE installer in debug mode and write "exit" to exit the installation. Then you got a linux shell you can yu to import and edit your ZFS pools.

Yes, work fine

Boot with Proxmox ISO
Advanced Options
Install Proxmox VE (Debug Mode)

In the console:

exit
/sbin/modprobe zfs
mkdir /mypool
zpool import -f -R  /mypool rpool

In the directory /mypool is the Proxmox pool for changing what needed

When terminate the operations to start again Proxmox:

cd /
zpool export rpool
reboot
