.mlt file not working

Hey… so i’m pretty new, and I was finished editing a video, i then decided to save it as an .mlt file, while simultaneously I was also rendering the video. Then shotcut stopped responding, I closed shotcut, reopened it and tried to open the .mlt file, and when I tried shotcut stopped responding. I have another file in the same location as the other one and it works fine. I would like to be able to open the file so i can get back to adding more edits.

If you can help that would be awesome.
