windows movie maker keeps crashing!

I recently started using the free trial version of movie maker. I was working on a video project for 2 days and it was working perfectly. On the third day of working on the same project, as soon as I imported a video the whole program shut down. when I tired to open up the software up again it asked if I wanted to restore the project because it had shut down unexpectedly previously. I clicked 'restore project' and my project was back. A couple minutes later when I added a photo, the same thing had happened and the program shut down. When I tried to open the software again, the same thing happened and I got the popup asking if I wanted to restore the project. This time when I clicked 'restore project' the software would shut down within 3 seconds of me clicking it. This has happened every time since whenever I try to 'restore' the project. I have also saved the project and when I go to open that, it will only allow me to open it in movie maker and it crashes every time I attempt to open it there. I spent a long time  on this video, please help! (my laptop runs on windows 10 and I have not updated the movie maker nor my laptop since I started the project)
