A just wonderful unknown error

After working on an SVG for a quiz I randomly got the error "Unspecified Fatal Error Encountered, Aborting" in Inkscape. The file is only 200kb or so and I haven't done anything much with the file besides adding shapes, text, editing nodes, and a bit of tracing with bitmap.

I don't have a clue as to why this is and I currently can't work on the SVG because it continues to bring up the error the moment I open the file. If anyone could help that would be very much appreciated. I don't want the SVG I worked hours on to go to waste.
