Both of my Gnome/Arch laptops no longer boot into Wayland - eviltoast

However, if I log in and immediately log out, Wayland is available on the login screen and you log in to a Wayland session.

This is identical on both my laptops, they are very different in hardware and performance. This started happening after updates about 3 weeks ago.

I have looked at logs and I can see the subsystems trying Wayland and falling back to X but I can’t see an obvious reason (probably my lack of experience at this).

Anyone else experienced similar?
