WordPress Database Disappeared, Asking for New Install

I’m running a local test environment using wampserver. I recently turned off the wampserver and when I turned it back on, one of my wordpress databases is missing. I have another database for another wordpress installation and it’s fine. I checked phpmyadmin and the database is there but empty.

Is there anyway to recover the database?
If I go through with the wordpress install, will it overwrite my old site?

I have the mysql log if that is needed.
