Manjaro wont boot (stuck at loading screen)

Hello again, I have some problem with my gnome manjaro. I did a pretty big pacman -Syu update the other day and now my system wont boot/load it gets stuck in the loading screen (with the three dots). I tried the other installed kernels but they all get stuck as well.

I have a live manjaro usb and also a bunch of timeshift files but i can’t get a terminal on the system to access them. How should i go about this?

Boot with the live usb and share some information:

manjaro-chroot -a #to access your installation from live media as root

For some reason it wont work, I get following output:

My /home /root and /swap are LUKS encrypted but they are mounted and can be accessed (except for swap). :confused:

see this for chroot crypto partitions

That’s loading screen, what you can do at this point is to press ESC and see last messages on your screen, also you can edit kernel command line parameters in grub menu to alter log level to something higher than default 3 and also remove “quiet” word from there in order to see moar messages during boot. Grub entry editing starts with pressing “e” button, and to boot with changed line press Ctrl + X.

As for live system, first unlock your luks partition(s) and then try chrooting to your decrypted root.
