Using the same method as before to enter commands (the TTY), rebase to an earlier build for a while, maybe wait until Fedora 40 builds are out this month before going back. I am not sure what’s going on but if this earlier build actually works for you, I would consider making an issue about it in Github issue tracker.
Anyways, try rebasing to the March 22, 2024 build in the TTY.
KDE:
rpm-ostree rebase ostree-image-signed:docker://ghcr.io/ublue-os/bazzite:39-20240322
GNOME:
rpm-ostree rebase ostree-image-signed:docker://ghcr.io/ublue-os/bazzite-gnome:39-20240322
In order to get back to the :stable channel and receive updates past this build, then you can have to enter in a host terminal:
rpm-ostree rebase ostree-image-signed:docker://ghcr.io/ublue-os/bazzite:stable
or bazzite-gnome if you’re on GNOME.
