Problem accessing localDB when moving application to new folder

Question

In a CRUD class I have declared the following connection string:

private static string dbConnection = @"Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=" + System.AppDomain.CurrentDomain.BaseDirectory + "\\PlexSeries.mdf;Integrated Security=True;Connect Timeout=30";

And the following GET method:

public DataTable Get()
{
     DataSet dataset = new DataSet();

     using (SqlConnection connection = new SqlConnection(dbConnection))
     {
         try
         {
              SqlDataAdapter adapter = new SqlDataAdapter();
              adapter.SelectCommand = new SqlCommand("SELECT * FROM dbo.Series", connection);
              adapter.Fill(dataset);
              return dataset.Tables["Table"];
         }
         catch (Exception ex)
         {
             MsgBox.Show(ex.Message, "Error", MsgBox.Buttons.OK, MsgBox.Icon.Error, MsgBox.AnimateStyle.FadeIn);
             return null;
         }
     }
}

When the application is run in the debug folder of the solution everything works fine.

But when I copy the debug folder to an other location ...

Upon getting to the line adapter.Fill(dataset), I get the following error:

Error Image

I tried to solve this by using a relative path to the database file but that didn't solve the problem.

In the previous version of this solution this was not a problem but that was build with Visual Studio 2019 and now I am using Visual Studio 2022.

Any tips on how to solve this?
