Look at your connection string: it's probably trying to connect using "IntegratedSecurity= true" or "User Instance=true"

User instances are only supported in SQL Server Express edition:
Editions and supported features - SQL Server 2017 | Microsoft Docs[^]
SQL Server Express User Instances - ADO.NET | Microsoft Docs[^]

If your connection string contains either User Instance=true or AttachDBFilename=..., then you're trying to use a user instance. You'll need to manually attach the database to your SQL Server instance instead, and update your connection string accordingly.
