5 hours long .mkv recording is completely corrupted

[Niuklear]

Hello, I had a very important recording that seems to be corrupted. windows movie player doesn't play it. VLC doesn't even show an error. I have 3 more of these corrupted files that make no sense. There was no interruption as far as I know while it was recording. I tried VLC conversion but it only gave me a 1kb files. I tried remuxing it to mp4. It worked on some but they were the least important ones. I also tried some ffmpeg solution, but that doesn't work either.

The corrupted ones don't have any length.

Is there anything else I can try?

@pushprajgaur fragmented .mp4 recording or .ts format is only alternative
