Screen turns off on HP laptop with Wayland on KDE Neon 6.6

Hi, I have an HP Pavilion 15-cs3073cl laptop with an i7-1065G7 iGPU. Upon logging into Plasma using Wayland, the display shuts off entirely and will not turn back on until a restart. This also happens in SDDM if Nvidia drivers are installed for the dGPU, but that may be unrelated. GNOME with Wayland is unaffected. X11 is unaffected. I’ve tried multiple Intel-specific fixes and even reinstalling the OS, yet this still happens. I’d like to use my laptop with Wayland again…

This didn’t happen below 6.6.
