Failed to mount devices, unknown filesystem zfs_member and LVM2_member

[slrslr]

Describe the bug
Debian 12 with KDE, ext4 system drive and a Timeshift 22.11.2 snapshot location set to a ZFS ext. drive causes disk writing on system drive and a KDE and some apps crashes when i sometimes cancel the snapshot attempt at stage "Estimating System Size" which seems to be stuck at estimating.

Hamburger menu option to display logs does nothing.

$  timeshift-launcher --verbose -v
App config loaded: /etc/timeshift/timeshift.json
E: Failed to mount device '/dev/sdc1' at mount point '/run/timeshift/210520/backup'
E: mount: /run/timeshift/210520/backup: unknown filesystem type 'zfs_member'.
       dmesg(1) may have more information after failed mount system call

similarly it also has problem with "E: Failed to mount device '/dev/dm-0' ... unknown filesystem type 'LVM2_member'." when changing snapshot location

I think that Timeshift ate around 3GB of my system drive disk space (judging based on "df" output before/after), I do not know where to delete it.

$ sudo timeshift --check
E: Failed to mount device '/dev/sdc1' at mount point '/run/timeshift/2214173/backup'
E: mount: /run/timeshift/2214173/backup: unknown filesystem type 'zfs_member'.
       dmesg(1) may have more information after failed mount system call.
