The system completely frozen in this screen.

SUMMARY:
I've installed KDE neon (user edition, with default themes, no extensions or customization). I updated my system, and when i restarted the system i logged-in, then plasma opened a black screen asking my kdewallet (i don't have one) and my wifi password. After i insert the wifi password, the system crashes and stucks in the presentation screen. My setup is: Intel Core i5-8265U, 8GB of RAM, 1tb (HD), 256GB (blitzwolf's ssd) <--- where the system is installed, Intel UHD Graphics 620.
I tried to reinstall the system, but the same thing happened again
STEPS TO REPRODUCE:
1. Install KDE Neon (user edition) in a ssd, with 400 MiB for boot, 8,5 GiB of SWAP and the /home installed in a HD
2. Update the system
3. Restart and Login

Edit:In the steps to reproduce i said to put 400 MiB for the boot, but i tested it now and this bug happen with any quantity for boot, i'm not sure if it happen installing the /home in the same drive, cais i didn't tested it.

Can you VT switch(control+alt+f2) when this happens?

If so can you get a snapshot of what's running
and ~/.local/share/sddm/xorg-session.log

No, i can't do it. Nothing happens when i press those keys. Anyway, it's a clean installation, i didn't even downloaded my things or changed any system settings. I think the services that are ruinning in background are the standard of the system.

Then I'm afraid that strongly implies your bug is lower level than Plasma and there won't be much we can do. X handles those keys directly.

You should be able to VT switch whilst on the login screen, from there you can install openbox or some such to have a session you can log into.

`journalctl -b -1 `
might list something interesting. It'll show logs of the last boot.

Oh just a thing: when you finish the installation of the system and it asks you to restart you can login normally, the bug happens when you update the system and restart by the second time after you've finish the installation.

Ah, i really don't know if in the login screen i can do it. I can't test it anymore cause i've aready installed another distro instead KDE Neon (OpenSUSE) in my computer to i be able to use it.
