Odd behavior after freezing

First off I'm not entirely sure this is a problem, everything is functioning at this point, but I ran into an issue that I don't quite understand either the cause, or the 'right' fix.

I think I ran into the freezing issue yesterday, my machine didn't lock after being left alone for some amount of time. 45+ minutes, but I thought nothing of it. I locked the machine when I noticed it wasn't locked. I typically leave it running overnight, so I didn't power it down or anything. super + l to lock the screen and walked off (the screen locked like nothing was wrong). This morning I went to unlock it, and it didn't unlock, the mouse would move, but there was no other response. Keyboard input was ignored. (hard to know if anything else was happening since it was locked)

I forced a power off, and it rebooted normally, until the login screen. I use 3 monitors and only two of them showed the login screen, where I would normally have the login screen mirrored across all 3. I logged in and most of the kde settings were set to the default. Wallpaper, panels, and the like. No latte dock running.

My conkys were up and running, as was telegram, which are the only two auto-start apps I've got configured.

I figured something had gone wrong with the forced shutdown, so I rebooted and mounted a snapshot. which rebooted into the same exact state, missing a display at login, default kde stuff.

I restored the snapshot since I was already there, and I wasn't going to miss any data.

Ran an update which executed cleanly it seems, same monitor/default kde state after reboot.

I used Garuda settings to restore Latte, and I re-configured wallpapers, log out and back in, 2 monitors on login screen, but everything restored as far as user GUI settings. Including my color schemes which are not default kde or Garuda.

Each time I rebooted and logged in, as soon as I logged in my 3rd monitor shows up like it had been there all along.

At this point everything is functional. It doesn't seem that I lost any settings, or application data/configs. The only setting that seems to have been lost is the wifi password, and I'm not sure if that was because I came across that popup before the keyring login pop up or if it was actually lost.

It's just strange, and I'm not sure why it happened, or if there's anything I can do to prevent it.

I never tried a diffferent kernel, I use zen normally, and have LTS installed, but I did not try booting into LTS.

If anyone has any ideas as to what might have caused this, or how it might be prevented in the future I'd love to hear them,
