System fails to load after update

From the tty I followed the advice again in the link and was able to do a full system update after using the command

update

After a reboot the DM will still not start although I can see now the kernel has updated to
5.14.9-zen2-1-zen

@jonathon I have followed the advice in the thread you linked, but I was unable to remove the drivers in ls -l /var/lib/dkms/*

sudo rm -fr 465.24.02 465.31 kernel-5.11.11-zen1-1-zen-x86_64 → 465.24.02/5.11.11-zen1-1-zen/x86_64

but they are still there

ls -l /var/lib/dkms/*
/var/lib/dkms/nvidia:
drwxr-xr-x - root 1 May 13:58  465.24.02
drwxr-xr-x - root 04 Oct 10:42  465.31
lrwxrwxrwx 35 root 24Apr 10:43  kernel-5.11.11-zen1-1-zen-x86_64 → 465.24.02/5.11.11-zen1-1-zen/x86_64
drwxr-xr-x - root 16 Aug 14:23  original_module

After this i tried

sudo pacman -R nvidia-dkms

and received this

target not found:nvidia-dkms

Im not sure how to proceed from here - I could chroot in but I would like to try to solve the problem.
