Shotcut crashes and shuts down when right-clicking a film in timeline

This has happened twice now within 5 minutes of each other. I was separating audio from the clips when I right-clicked on one and SC went black and closed. When I reopened it, absolutely everything was gone, I looked in auto save, but the only mlt files there were of the one same clip that I first put in. When I looked at opening up my manual saves, they said that files were missing, so I replaced them and had to completely start over on my work. Then, about 3 minutes later, the same things happen, only now my manual saves are acting up, and they only show that one same clip again when I paste them into Shotcut. Please help.
