Forza Horizon 4 "engine synth" .zip files, can not extract

[Kraken]

I've uploaded a file for reference. With the recent release of a FH4 ultimate edition file dump by fitgirl and others, these files finally have rid of the MS store protection, however, something else is going on.

I'm trying to extract the engine audio files from this .zip folder (which you can do from Forza Horizon 3 no problem) however, there appears to be unknown errors going on during extraction, this is for all the files by the way. I tried using quickbms with the forza script to no avail, anyone have any idea what the error/issue is?

Using winrar and 7zip it just says "unknown method, no files to extract" in winrar and 7zip "unsupported compression method".

Any advice on what's missing i'd greatly appreciate, been waiting so long to try and use these sounds for mods .

If you are able to extract them, do you think you could send me the sound effects for Flying Scotsman, i’d like to use them for a project.

No one has any clue how to access/extract the audio inside so it plays naturally?

I'm a noob but they files could be compressed in a different way I think. Meaning they need to be extracted not just with winrar or 7zip since that will give errors. Can you figure out if that is true?

I believe from having a look it may be using method 22 encryption or something? I am not sure if anything can yet extract it, or there is an updated dumped version of the FH4 files to extract.
