[Crash] Launching ANY application logs me out of my Fedora 40 Workstation

Hi there. What you’re describing looks similar to this issue.

Does the below answer solve your problem too?

Gnome apps cause WM to fail on Fedora 40

Sounds like: 2292321 – gnome shell wayland sessions crash when any app is launched Try dnf downgrade mesa* Then reboot and see if that resolves the issue. With KDE, using SDDM you get a black screen. Hopefully, they’ll get this resolved soon and pushed to stable. If that is indeed your issue, you’ll need to stop updating until it’s fixed or place an excludepkgs=mesa* in your dnf repo files.
