Lost data

I edited my audio on audacity and saved my audio, but when I opened up the file again a week later half of the audio from my track was missing. Some audio was saved but most of it was just replaced with silence. If anyone knows how I can get this audio back that would be appreciated. Thank you.

Which version of Audacity are you using? (look in “Help menu > About Audacity”)

Were there any error messages when you opened the project? If so, what did they say?

I’m using 2.3.3. an I had no error messages when I opened it.

The current version of Audacity is 2.4.2 https://www.audacityteam.org/download/windows/

I think the project must have been damaged at some previous time, otherwise there would have been an error message. I don’t think it will be possible to recover the lost data unless you have a backup.
