Same here. In unstable and testing …
EDIT:
But maybe “archlinux-appstream-data” was the problem I don´t know…
Downgrade mesa solved.
For me todays update broke system (in VM virtualbox).
No boot to SDDM, Kernels 5.15 5.19 6.0 6.1
Tried different things, nothings works. “Startx” get a lot of driver errors.
VideoDrives mhwd looks ok.
Only branch change to stable solved for me…
In unstable (other VM vitualbox it looks like the same …)
EDIT:
Probably the downgrade of mesa is the simple solution !
(See unstable)
