iTunes playlist disappeared 2021

Solved: All of my songs have disappeared - The Spotify ...

Free community.spotify.com

I just restarted my computer (Windows 7) and my entire starred playlist disappeared! Almost 3,000 tracks disappeared! I tried to log in and out using my Facebook, email, different username, etc. as I found was suggested on the community in a few places and it didn't do anything. The playlist is also empty on my iPad. Can anyone help me!?
