Cannot save movie in Windows Movie Maker

I am simultaneously receiving the error below when trying to save a movie in Windows Movie Maker. I am trying to save it as the default Movie Maker Project file but it still failed. I also tried to run the latest update but it doesn't change anything. Can someone please help me?

Your movie was not saved successfully.
Windows Movie Maker cannot save the movie to the specified location. Verify that the original source files used in your movie are still available, that the saving location is still available, and that there is enough free disk space available, and then try again.
