Audio files corrupted to zero bytes after iCloud sync on Mac

Hey, just recently I was recording two songs with my band. I just recorded on my Mac internal disk because I want it to be reliable and fast,I did not really know or understand that files are uploaded to the cloud all the time, now I know the problem with opening files was about the files being in the cloud, which kinda sucks, especially if you are somewhere you do not have internet.

The next day I wanted to edit our songs and the audio files were corrupt, it says the size is zero bytes, is it possible to force download them again?

The problem/question I have is, are the files doomed or are they saved somewhere, I mean they should be, after recording we still listened and edited some things ... ?
