Closed issue by OoLunar on void-packages repository

https://github.com/void-linux/void-packages/issues/50393

Description:
### Is this a new report?

Yes

### System Info

Void 6.6.30_1 x86_64 AuthenticAMD uptodate rrrmFFFFFF

### Package(s) Affected

Unknown

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

None found.

### Expected behaviour

- I successfully boot up my laptop
- SDDM's login screen appears
- I successfully login
- My desktop appears (fails)

### Actual behaviour

Once I login through SDDM, my desktop appears for 1-3 seconds before crashing. KCrash appears to try to launch `plasmashell` again as my desktop will appear one more time for another half second before crashing once more. Once everything settles, I am left with a black screen, completely unable to access my system tray or any of my desktop applications.

I am currently able to access my applications through a desktop shortcut. I launch `flameshot` and take a screenshot of my black desktop, attempt to save the file. Once `nemo` prompts me where to save the file, I click "Open location" via the right click menu. Once `nemo` fully launches, I'm able to open up `gnome-terminal` and start `firefox` or whatever other applications I may need.

Ctrl+C and Ctrl+V (copy and paste) are still very unreliable (may be unrelated).
When any application attempts to use `libnotify` (or presumably attempts to send a desktop notification in any sense), the application will freeze before it's forced to be killed by me.
Alt+Tab still works as expected.

### Steps to reproduce

1. Update from KDE5 to KDE6
2. While I did not take any explicit actions, there may be other steps that were performed without my knowledge. While I was upgrading, a lot of packages failed to upgrade due to package conflicts caused by the Void packaging servers not having certain versions of packages available, such as `plasma-nm`. Additionally a lot of packages were removed without my prior knowledge, such as `NetworkManager` and `dialog`. I personally believe this may have significantly contributed to the problem, though I have no proof.

Please let me know if any additional information is required. I am considering switching away from Void to Arch, however I happen to very much enjoy using Void and would prefer to resolve this issue first.
