Black screen in video player

I’m new to Cubase so not sure if this is a bug or just me. I’m using Windows 10 22H2 and my PC is Intel(R) Core™ i7-4790 CPU @ 3.60GHz 3.60 GHz. I have 32GB of ram. I am using an Intel 4600 graphics card. I have tried MP4 and Quicktime video files. They seem to load and the sound files and thumb nails appear. When I play the video in cubase the clock on the video player ticks over ok but the screen remains black. Any advice appreciated. Thanks.

oh, and I am using Cubase 13 Artist.

Update; I have downloaded Cubase 12 and the video’s play ok in that. FYI.
