Operating System: Linux 6.10.10-200.fc40.x86_64 x86_64

-- Information about the crash:
On my fedora 40 x86_64 system, I try to login from an display manager (lightdm) into a plasma/kde wayland session. This is not possible at present.

In addition, starting plasma/kde after non-graphical login with startplasma or startplasma-wayland is not possible as well.

plasma/kde was functional 3 weeks ago but has suffered from an RPM fedora update.

The crash can be reproduced every time.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Illegal instruction
