Can't start gdm after update.

I used my computer normally yesterday, then updated the system, rebooted my windows partition, rebooted back to my linux partition and when I booted I got the gnome "Oh not! something went wrong" message.
I tried

pacman -Rncs gnome gnome-extra

Followed by

pacman -S gnome gnome-extra

And then reboot, but I got the same error.
I then removed all my gnome extensions but it still doesn't work.

When I run

systemctl start gdm

I get

Failed to start gdm.service; Unit gdm.service failed to load: File exists. See system logs and 'systemctl status gdm.service' for details.

This is the output for "systemctl status gdm.service"

● gdm.service - GNOME Display Manager
   Loaded: error (Reason: File exists)
   Active: inactive (dead)

The output for

systemctl is-enabled gdm.service

is 'enabled'

I'm not sure what to do, please help

Re: Can't start gdm after update.

can you have a look through your journal to see if there is an entry similar to

set 22 12:16:44 arch-desktop gnome-session[432]: gnome-session[432]: WARNING: Application 'gnome-shell-wayland.desktop' killed by signal 11

This should find such an entry

journalctrl -b | grep gnome-shell-wayland.desktop

This is the recent thread I am basing this off which seems similar https://bbs.archlinux.org/viewtopic.php?id=202743
