Need help Hosted Server Database

Hi all,

I have a strange problem with a self-hosted server (Free Trial Enterprise Edition), I was configuring the SSO option and suddenly I lost all access to the organization vault (I was the owner) as well as all the profiles administrators while normal users can access it without any problem?
When I try to add the license file, I get the message “Failed to fetch” error.

Can I access the database and see if the users still exist?

thank you in advance
