Yes, probably.

I reinstalled VP from Microsoft Store earlier today when I first got trouble. Don´t know which version that is. But I got the video back to 3 minutes somehow now.

Got the same problem, I think. Can´t export project to videofile mp.4 I get 13kb labelled as mp.4 but with the icon of mp.3 instead Lossless export worked. *edit* But a 3 minutes long video turned out to be 13 minutes with 10 minutes of nothing.
