System information of my notebook (openSUSE Leap 15.2):
KDE Plasma: 5.20.5
KDE Frameworks: 5.78.0
Qt: 5.15.2
Kernel: 5.3.18-lp162.60
OS: 64-bit
Processor: 8xIntel Core i7
Memory: 7,7 GiB RAM
Graphics: Nvidia Quadro 3000M/PCIe/SSE2

The system works fine with plasma. However, when selecting both Wayland or Full Wayland as a Desktop Session the system freezes instantly. Only black screen, keyboard completely disabled.
Any idea what might gets wrong. Is Wayland hardware dependent.

Regards,
Bojan
