Audacity just deleted my project

I am using version 2.4.2.

I had been working on a project for about five hours, saving repeatedly as I went. Audacity crashed as I tried increase to the input volume. When I relaunched, I saw my whole project there, but a dialogue box appeared telling me I needed to restore the project. I clicked restore, and everything disappeared, leaving me just with an empty project. Is there any way I can recover what I lost?

I see this post is a few days old. Do you still need help with this? If so, what is the situation now?
