Unknown Connection String.Name: 'core' error

Question

I was setting up one of the sites in my local and I am facing the Unknown Connection String. Name: 'core' error when I try to browse the site. Have imported the databases into my local SQL management studio.

Here is the connectionstring file :

 <add name="core" connectionString="Data Source=xxx;User ID=sa;password=welcome1@;Database=sitecore-core-2022-3-15"/>
        <add name="master" connectionString="Data Source=xxx;User ID=sa;password=welcome1@;Database=sitecore-master"/>
        <add name="web" connectionString="Data Source=xxx;User ID=sa;password=welcome1@;Database=sitecore-master"/>
        <add name="custom" connectionString="Data Source=xxx;User ID=sa;password=welcome1@;Database=sitecore-custom"/>
        <add name="web2" connectionString="Data Source=xxx;User ID=sa;password=welcome1@;Database=sitecore-master"/>

The log is not generating any error related to the above issue it only says as below

Can anyone please suggest how do I need to resolve this issue?

Thanks
