Hi, thank you for your bug report. We would need some more information to debug the problem. When your session fails to start, can you switch to the virtual ttys via Ctrl-Alt-F3? If so, could you provide the complete outputs of `journal -b`?

Could you also provide the Xorg logs at /var/log/Xorg.0.log?

What graphical processors are you using?

Thanks again!

Did you mean journalctl -b?  It is almost 15,000 lines, and I am getting an error when I tried to include it in my reply- bugs.kde.org thinks that it is spam (not surprising).  Xorg.0.log is about 750 lines, as well.  I am going to add them both as attachments.  I am using an AMD Radeon Pro WX3200 series GPU.
