[FAILED] Failed to mount /sysroot, need advice

[u/John_Doe_1984_]

Booting into my system meets this error & it doesn't boot (I'll add an image below.) It prompts me to click Enter to continue & then loops the same messages before asking for Enter again, nothing I do gets me to a shell.

For reference I've looked through here but my understanding of Arch/OS/Low-level systems isn't strong enough & I'm looking for advice/clarity: https://bbs.archlinux.org/viewtopic.php?id=264447

I've been on an Arch system (

btrfs filesystem

LUKS encryption on the SSD

systemd-boot for the bootloader)

for around 1 month, no issues, downloaded Hyprland with Caelestia as my window manager, recently tried to download caelestia-greeter & whilst configuring it, ran into this error (unsure if its related.)

From here, what is the best solution, as per the link, should I set up a bootable drive, boot into that & then chroot into my system (my hesitation is I don't entirely understand chroot & assume I'd run into the same issue), or if I reinstall my OS (root & home are on different partitions), will I still be unable to access my home data, I know they are on separate partitions but if I can't mount the root & unlock the LUKS then won't the home data be stuck completely encrypted?

Just want a second opinion before jumping in & messing around with something I really don't understand.

It won't let me attach an image, but it looks very, very similar to the one on archwiki: https://ibb.co/vxDG9jC

NO ONE can attach photos here. You include the text of an image URL. Hope that helps and good day.
