Bug: Media that causes Motion Tracking problems in Vegas 22 build 122

The media file I uploaded to google drive causes Vegas 22 build 122 to freeze as soon as motion tracking begins forward from the first frame using the "Perspective" option. The "Location" option does not have a problem.

It seems that if the first frame is significantly different from the second frame because of too much motion, there's a freeze. Normally when there's a scene change, Vegas will stop motion tracking at the point. If it happens to be between the first and second frame, then that's a condition not accounted for, and an error occurs, and control is lost of Vegas.

@Robert Johnston The freeze is caused by Motion Tracking returning a Low Track Count and has been reported. A workaround is to start mid clip, track forward and then backwards. Or track backwards from the end. I've just tried both methods and no freeze. Another way is to avoid the big jump between the first three frames by trimming the first two off. That works as well.
Personally, if you're just tracking the balloon, I'd use Location mode. Much more accurate than Perspective.

@Jack S I know all the workarounds. I was actually trying to help someone on a different thread with a motion tracking problem. I just happened to pick that balloon clip out of the hat and immediately ran into the problem. So infuriated was I.
