Could not open EFI_OPEN_SUBVOL_PROTOCOL on fs driver - EFI_UNSUPPORTED

[itsTyrion]

I wanted to try btrfs + quibble in VMware Workstation 16.

What I did: First, I made 2 Windows 10 VMs with BtrfsWin installed.

I powered off VM 2, attached the virtual disk to VM 1, ran ntfs2btrfs and rebooted to make sure everything is still on there, which seemed to be the case.

Then, I mounted the ESP of the target VM, copied the quibble files into the ESP's root, unmounted the ESP, and shut down.

I then booted up the target VM, chose "Boot from file" and selected quibble.efi, which opened fine and hit enter.

Sadly, this is all I'm getting.

Problem with quibble, problem with the VMware EFI or a layer 8 issue ;) ?

Edit: Now I had a new boot device and it "worked" a little bit (No Quibble UI, Automatic repair and BSOD)
