here is video reference  you should try this 

If you receive an error that the database is in use, try to set the user to single user mode: USE master; GO ALTER DATABASE Database_name SET SINGLE_USER WITH ROLLBACK IMMEDIATE; Then try the restore with recovery command again. Also, make sure you are on the latest service pack or cumulative update.

In most cases this error raise due to version conflict i.e your odoo new odoo instance is Odoo 15.0+e-20220307 and the database you have is of different version.

This can be resolved by destroy the current odoo instance and reinstall the previous version of it, which I personally don't recommend.
Or

Restore the database from command line, how to do it, the answer is here
