Hi Jack! I don’t know if this will help, but I was having a similar issue with the crosshair not showing up after applying match move. This was my solution, and I hope it helps you as well. I went up to view on the toolbar and made sure that “show overlays” was checked. This brought the crosshair into view and sourced my video in the inspector panel.
If this had nothing to do with your issue I apologize in advance! 🙂 I’m pretty new at this.
Hope to hear that you figure this out soon.
Take care!
Andrea
