Deutet auf ein Problem mit DirectX bzw. dem Grafikkarten-Treiber hin. Installiere mal die neueste Version von DirectX:
https://www.computerbase.de/downloads/systemtools/directx/

Falls die schon drauf ist, einfach nochmal installieren.
Sollte sich das Problem dadurch nicht lösen lassen, aktualisieren bitte den Grafikkarten-Treiber.
