Failed to mount Mount units at boot

I was facing the issue that my kde Plasma didn't let me sign in and gave me the error message:

The current theme cannot be loaded due to the errors below, please select a different theme.

file:///usr/share/sddm/themes/breeze/Main.qml:12:1:plugin cannot be loaded for module "org.kde.plasma.core": Cannot load library /usr/lib/qt/qml/org/kde/plasma/core/libcorebindingsplugin.so: (libunistring so 5: Cannot open the shared-object-file: File or directory not found)

So I reinstalled the breeze package, made a system update (pacman -Syu) and rebooted my system. But now every time I try to boot I get:

I tried looking for advice already and found on an ubuntu forum that it might be missing snap files but I don't know how to go about this because it doesn't seem like I'm able to open a command line or anything (ctrl+alt+f2 doesn't work).
Any advice would be more than welcome.

Welcome to the forums. Please edit your post and add [ code ] [ /code ] tags (without spaces around code to make it easier to read.

Can you boot the multi-user.target?

Which display manager are you using?

Hi, thanks for the reply.
No, I cannot multi-user.target. It fails already while it's checking the drives.

I'm using Xorg.

I hope this is of any help.

Boot the live ISO, mount your partitions and arch-chroot into the system (as you did when installing Arch).

Once in the system, disable all of the snap mount units in /etc/systemd/system/multi-user.target.wants/.

I don't use snap, but it seems poor design if a failure to mount snaps prevents booting the system.

Hopefully that will let you boot the multi-user.target to troubleshoot the system.
