This issue is the same issue created by me here: Setting up Cryptsetup on a separate /home partition goes into emergency mode
The solution that I found out was sort of an “Ostrich Algorithm” solution, but now I need to encrypt. Thus, I am opening this issue again in a new post since the old issue was closed. Pasting the same issue description down here, along with the output of “journalctl -b” and “/etc/crypttab” as recommended by @arvidjaar in the previous post (UUID for cr_home might have changed since previous post, but the mount points and setup are same):
/etc/crypttab
cr_home UUID=9d4dcb77-c318-4ef1-bb04-8cbf0fb6e4f5
jounralctl -b

Hi,
I recently made a fresh installation of Tumbleweed (snapshot 20241109). While setting up the system, I created 4 partitions:
- /boot/eft, FAT, 0.50 GiB
- swap, swap, 32 GiB
- /, btrfs, snapshots enabled, 150GiB
- /home, ext4, rest of the space.
Now I face a bizarre issue. When I turn on my system, it sometimes boots up just fine, and sometimes it fails to boot, and goes inside emergency mode (which probably meant something failed in fstab). Both issues happen after asking the cryptsetup password. Going inside the emergency mode by entering the root password, I ran the following command to see what failed:
systemctl --failed -l
UNIT LOAD ACTIVE SUB DESCRIPTION
● systemd-cryptsetup@cr_home.service loaded failed failed Cryptography Setup for cr_home
Legend: LOAD → Reflects whether the unit definition was properly loaded.
ACTIVE → The high-level unit activation state, i.e. generalization of SUB.
SUB → The low-level unit activation state, values depend on unit type.
1 loaded units listed.
I have setup other openSUSE instances (both Leap and Tumbleweed) with a similar setup before (infact there is Leap 15.6 in my laptop which is setup exactly this way), and this has never occurred.
Here is an output of the cryptsetup logs:

And here is my fstab file if it helps:
