In addition to that, you wouldnt be able to see the issue just from a project, as you would need to try to animate a mask to see if it crashed on your end.
What you could do is take a 10 second clip of someone and apply a mask to isolate them from the background. Apply keyframes every half second or however often is needed for how much the person moves. Go into full screen clip previee mode to move the points.
That should tell you if its an issue with VP or just with my system.
