Sorry for the lack of information.
I have sddm and kde plasma. Im not sure about the login manager, where can I find it?

Wayland package and the other components for it that were previously installed with the system

If you havenā€™t reinstalled already, this are things you can try.
If you use the sddm greeter.
Go to system settings type sddm in the search box and click on the option given, next on the behaviour option on the top of the window, and see if autologin gives you a wayland option, tick the boxes and click apply, and reboot. If you are in wayland now, donā€™t start anything e.g. Vivaldi to avoid the Kwallet popup to logon , next reverse the changes you made, click apply and reboot. Now see if you have got the options back on the login screen.
If that doesnā€™t work creating a second user might work.
As a last resort (that I can think of that is) go to this page.

And next go to paragraph 2.12 (note:you will have to create the mentioned 10-wayland conf. file yourself).

Reinstallation did not give any results, sddm settings only show X11.
Creating the 10-wayland.conf file didnt help either. I entered the lines into the file as described in section 2.12.1

Tried downgrading nvidia drivers and creating a new user, still doesnt solve the problem

Is plasma-wayland-session installed? Try running pacman -Syu --needed plasma-wayland-session

12 
error: target not found: plasma-wayland-session
13

Sorry, it was only a guess based on plasma-x11 session.

14

Try reinstalling plasma-workspace

15

The solution was simple all alongā€”thank you

Iā€™ve run into this before when switching between Wayland and X11. Sometimes the display manager configuration gets a bit stubborn. It might be worth checking your /etc/gdm/custom.conf (if youā€™re on GNOME) to see if ā€˜WaylandEnable=falseā€™ is uncommented. That often hides the session selection gear icon entirely until itā€™s toggled back.

Just for your information Plasma is not Gnome and uses SDDM not GDM, and this thread seems to have been about a user that missed a package that in normal circumstances should have been installed, how it happened is a total mystery to me, because we donā€™t know the complet story behind all this.

More likely, one of the files from that package was deleted and reinstalling that package restored the missing file.

In this case, /usr/share/wayland-sessions/plasma.desktop

19

Yes I agree but I meant to say how this package was deleted is a mystery to me.
