SDDM hangs on KDE Plasma (X11)

Hello everyone,

first issue I actually need help with. Please bear with me as I am not a pro at all. If you need any additional info/logs I will gladly post them.

Situation:
A few days ago I noticed that whenever I try to log into my Plasma X11 Session with SDDM that the whole screen freezes. I can put in my password, press enter and then the whole screen will freeze forever. I can still move my mouse around. And I can also switch to a terminal with "Ctrl" + "Alt" + "F3" log in, and also switch back to F2 where the login session resides. When switching back the screen will be black but I can still move my mouse around.

What I tried:
- Reinstalling SDDM

I am kinda clueless what the problem is. My guess is, that it might have to do something with my Monitor Setup and my Nvidia graphics card. But everything worked smoothly. Maybe it was me being a dummy and running the ML4W hyprland setup? Maybe that messed something? I had this same issue around 5 months ago and I ended up reinstalling arch linux, which i dont want to do again.

Thanks in advance!

Your session rather than SDDM?

I can still move my mouse around.

Suggests the X11 server is fine but KDE/plasma is not.
Does anything show up when you suspend the compositor (SHIFT+alt+F12)?

Anything in the system journal? Crashes? Errors?
What processes are actually running after the login? kwin_x11? plasmashell?
