Recording video using surface book froze in between and the mp4 video is now corrupted and unplayable. How can I restore the video?

My video is corrupted. When I try playing it using any media player it gives this error:

Can't play

This file isn’t playable. That might be because the file type is unsupported, the file extension is incorrect, or the file is corrupt.

I tried different free online video fixers but to no avail did they work. One gave me a compressed 3 min version of my 37 min video.

What else can I do to restore the video? It's very improtant for my work
