Projects are getting deleted

[Utomneian]

i also have this problem, but on Windows 10. every other time i save and close Ableton, the next time i open it up, my last project is gone, greyed out in recent, and no trace of it in my projects folder. i had gotten in the habit of manually saving backups to a completely different folder before i close Ableton.

Hi, be aware that this is an old thread and that these issues are most likely caused by factors outside of Ableton - such as cloud storage etc.

I managed to replicate the issue. Been happening to me for a while.

In this project some of my samples are hosted on google drive.
I used collect-all-and-save, and got an error message that file X could not be saved (the file is unavailable due to cloud storage for some reason).
After the error message, my project file was completely deleted.
I've repeated this multiple times and got same results, even after removing google cloud sync.
Only after deleting those stale samples was I able to properly save the project.
Sounds like a real bug in Ableton, nothing more.
The file should never be deleted.

In your code you could be opening a file stream first and only then collecting the samples. At this time, the original file is already replaced with a new pending one, and since it's probably empty, it gets deleted.
