Help! OpenSUSE Tumbleweed with KDE on Raspi4

Hello opensuse folks, I own a rasperry Pi 4 8GB and would like to use it a media center with opensuse to watch Youtube and Amazon Prime Video. Did run Raspberrian Py till a few days ago Prime did deny service on that chromium. What can I do to run openSUSE with KDE on it like on all my other computers? I did install a tumbleweed kde image from https://en.opensuse.org/HCL:Raspberry_Pi4. The only things I see after booting is a mouse pointer and a ksplahmql crash window (Segmentation fault). What can I do? Thanks for you help, Sandra
