Could not unmount target system root /, calamares failed to finish

Tried twice, but failed with the same error.

iso used is xfce+dinit
artix-xfce-dinit-20240823-x86_64
iso was booted via easy2boot usb boot stick, linux type.
on artix boot screen , choose boot from cd/dvd.
upon installation options, I choose to use offline,
 install to a dedicated nvme drive, whole drive, manual partition as follows:

GPT
512 MB /boot/efi  FAT32 with BOOT flag.
165GB /home btrfs
4GB swap linuxswap
16GB /var xfs
the rest about 55GB allocated to / , type btrfs
there's about 17MB at the end of the nvme not allocated.

Is there a bug in the installer or something I chose is not right? Thank you.

Hi yes I've tried ext4 for / and it was smooth all good.
So it was btrfs combined with the installer causing trouble.
I noticed that the various linux sub folders in / seemd to be utilising btrfs's special feature , they are not plain folder. (can see they show up as @ @abc etc when mounted). And this might causing the umount error , I saw multiple sub folders under / were mounted when the error happened
