Crash-Report from KDE

For some reason I could not send the error with the crash-reporter, I am doing it manually. Following is the content from the kcrash file.
----------------------------------------
Application: kdenlive (21.08.0)

Qt Version: 5.15.2
Frameworks Version: 5.85.0
Operating System: Linux 5.13.8-1-default x86_64
Windowing System: X11
Drkonqi Version: 5.22.4
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed: just start the application on a fresh openSuse Tumbleweed installation

The application shows an error stating that the preview window cannot be loaded, but no real cause is given. It is mentioning that it could be a driver issue...I am running the NVIDIA driver.

The crash can be reproduced every time.

-- Backtrace:
Application: Kdenlive (kdenlive), signal: Segmentation fault
