Hang on resume, KDE Plasma 6.8, NVIDIA

After Plasma 6.8 forced the switch to Wayland, always get a black screen on resume from suspend. Can't switch TTY; have to hard reboot.

A script reloading nvidia modules and restarting sddm automatically (suggested here) avoids the hang, but obviously restarting sddm loses my session (and that guy doesn't know why he's doing what he's doing, he just had a chatbot generate a bunch of stuff).

Journal shows:

nvidia-modeset: ERROR: GPU:0: nvHandleCpEventDeferredWork: displayId 0x10000 invalid

Searching seems like there might be a bug with losing displayport connections in nvidia-open since 615, but info is sparse.

If I downgrade to 580, I still get a black screen. Sometimes if I wait a bit and keep using the mouse/keyboard, the display will come back. Other times, it remains frozen. The journal doesn't contain the error above, but nothing else is jumping out at me, or differs between successful/unsuccessful resumes.

TIA.
