Hey, today my Manjaro doesn’t boot like the other days and throws this error while booting:
[65.094453] systemd[1]: Cought , core dump failed (child 337, code=killed, status=7/BUS).
[65.095120] systemd[1]: Freezing execution.
After some restarts the problem still there, so I hope someone can help me 
It‘s a bit hard to execute commands without access to a shell
boot on USB iso manjaro ,
open a terminal and a browser on this topic
sudo manjaro-chroot -a
journalctl -b -1 -p4
exit (end chroot ) and provide also
inxi -Fzajournalctl:

5.13 is EOL. Switch to a supported kernel:
sudo manjaro-chroot -a
sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syyu
sudo mhwd-kernel -i linux510
exit
Then reboot into 5.10 (Press Esc during boot to get into grub menu and boot with 5.10)
Double check your running kernel is not 5.13 then remove it:
