Unable to boot Bazzite 42.20250513

System:
OS: Bazzite
Version: 42.20250513 (digest: sha256:20faa2b2...)
Hardware: Lenovo, AMD Ryzen 7 8840HS with Radeon 780M
Boot Mode: Secure Boot enabled
Display Manager: sddm
Session: KDE Wayland

Problem:
After upgrading to the 42.20250513 image, the system boots to a black screen (I think it's TTY1 with blinking cursor). No graphical session is visible or responsive. Can't get to TTY3 or anything.

Solution
I did these things, and one or a combination of them fixed it
sudo rm -rf /var/lib/sddm/.cache
sudo rm -f /var/lib/sddm/.config/kwinrc
sudo rpm-ostree rollback
sudo rpm-ostree upgrade
