Won't boot after update

This was a while back, I’m just trying to fix it now.

I installed the updates that had come up and the next time I restarted the pc got this message, then my whole PC locks up and I have to hold the reset button.

Warning: /lib/modules/5.10.2-2-MANJARO/modules.devname not found - ignoring
mount: /new_root: unknown filesystem type ‘ext4’
You are now being dropped into an emergency shell.
sh: can’t access tty; job control turned off
[rootfs ]#

but there is nothing I can do, like I said it locks up the PC.

Any ideas?

This is an i5 with a GTX 1050
