Soft-Locked after entering my password.

My notebook is connected to my 4K (4096x2160p) TV via a PS5's HDMI, the image appears duplicated, with the difference being that only the TV is interactable, and trying to log into the account from there freezes on that screen.

I see something similar on my machine.
External monitor via HDMI, notebook lid is closed: login doesn't work.

A workaround seems to be to move the mouse to the not visible notebook display (to the left and out of the monitor) and *click* there once.
After that typing the password blindly works for login.

I'm having the same issue on my machine. When logging in on my main monitor connected via Display Port - the SDDM hangs after entering the password and confirming it. The password can only be entered on the second monitor connected via HDMI. 

Also the Splash screen after login seems to stay longer than before the KDE 6.2.1 update. I can hear Thunderbird notification coming in but the Splash screen is still visible.

I'm having the same issue on my machine. 
* I use Arch on a laptop.
* The laptop is connected to an external monitor with a displayport cable.
* I use the external monitor as main monitor.

Till the latest update, which brought me among other things "plasma-* packages 6.2.1-1" for example, login into kde plasma (x11 session) was not a problem.

But now nothing happens if I insert my password at the KDE login-screen (default breeze).
The workarourd is to unconnect the DP cable, make the login and after that connect the cable again.
The 2nd monitor works propely. (I am using it now)

Same issue here, on a desktop with arch, with Wayland.
Primary screen is on HDMI, second screen is an old VGA with a VGA -> Display port adapter, both 1080p connected to my RDNA3 AMD card (in case it is somehow connected to the problem).
When I start my PC, after typing the password, the login screen on my primary screen freeze, and I need to type the password on the second screen to login. Also the boot time seems to be longer than before.
The problem is not here when I manually lock the computer

Can confirm the issue.

After switching the SDDM theme from "Breeze" to "Maldives" the login worked again. After switching back the error also came back.

Maybe this helps finding the issue.

This worked also for me. Changing from <DEFAULT> "Breeze" SDDM theme to "Maldives" fixed the issue! I really don't like the look of the "Maldives" SDDM theme because i am more a dark theme minimalistic lover - but thank you so much for sharing!

Same here, two monitors connected per DP. When entering the password, it automatically selects me (wrong) second screen first, where nothing happens after entering the password and pressing enter. I then move the mouse to the main monitor and enter the password there and can log in as normal.

Same bug here but on a desktop not a laptop, when I log in if I try to login from main screen nothing happens it just stays there with the password "greyed out", if I try to log in to any of my left and right monitor it logs in. I am on arch
