Zoom recording didn't convert properly

I have an important zoom recording that I recorded to my mac. It didn't convert properly, and I tried to convert it with any app that would work... I forgot it was a video (I meant to just record audio), and opened it in the music app to see if that would work. Of course it didn't, and now it say it's a "music document" and opens my music app when I try to open it, but doesn't play anything. 

I tried using converico online but it didn't recognize the input file. I went back to zoom, but since I put it on my computer, it tries to open it from my desktop, and it opens the music app (but nothing appears). 

Did I just completely blow any chance of listening/viewing it? Is there any way of converting it to something I can use? The extension still says .zoom
