Recordings not converting either automatically or manually

I had a Zoom meeting today that was recorded on my computer. My computer crashed at the end of my call (that's a whole different story). When I opened Zoom, it said I could convert my meeting. I clicked on it to convert, but it just sat at 0% and didn't move. So, I opened up the file location and tried to convert it manually - again 0% with no motion. Is there any way to convert the meeting without using the Zoom app? Or do you have other suggestions?
