How can I extract a jpeg from a corrupted raw file?

I have a corrupted raw file I want to recover (click here to download it if you want). I think the jpeg inside the raw file is intact, so I've been trying to extract it in different ways, using free software like ERawP or even writing a simple python program

However the problem with these methods is that neither the programs nor the Python libraries see the file as a raw file in the first place

Any advice?

EDIT: the photo was taken with a Fujifilm camera in case that's relevant

Thanks

Here is the code I was using:

import rawpy
import imageio

path = '/pathToFile/_FFF9198.RAF'
raw = rawpy.imread(path)
rgb = raw.postprocess()
imageio.imsave('findMe.tiff', rgb)
