Can’t login to Admin panel after restoring snapshot

Hi,
I was using the plugin for other sites too, but today, I was making some changes and created a snapshot before that, after changes I wanted to restore to the recent snapshot.

Restoring was successful but when I tried to access login, I found Fatal Error: https://www.dropbox.com/s/rcmvk3l9wzneome/Capture%202020-08-11%20at%2012.37.17.png?dl=0

Do you have any idea?

Thanks in advance
