"Failed to Open" MLT File

I’ve been editing a video for a few weeks now. I was editing it earlier, closed Shotcut, just tried reopening it, and now it’s not opening. It opens a blank project (“Untitled”) and gives me a “Failed to open [File Path].” I haven’t changed the path and all of my work is missing. How can this be fixed?
