Video Editor exporting pixelated/distorted videos

Hi,

I was recently splicing together some videos in the Windows Video Editor app and came across an issue when exporting. The exported video file is distorted and pixelated with black areas across it (image attached below). It previews perfectly and only seems to impact it when exporting. The computer I'm using is operating with the original graphics card, so don't thing that is the issue. Any help would be appreciated!
