Corrupt Logic files after OneDrive backup on MacBook Pro

Some years ago in my limited knowledge, I thought I could backup my logic files via onedrive. Today, 60% of my files show as corrupted and I cant open them. Just bought a new mbp M4 and the files are on my 2017 touch bar mbp. They won't open on the older and can't transfer them due to the issue after I've downloaded them...says files are corrupt 🥺

Any thoughts as to how I can salvage these files?
