************** JIT Debugging **************

To enable just-in-time (JIT) debugging, the .config file for this

application or computer (machine.config) must have the

jitDebugging value set in the system.windows.forms section.

The application must also be compiled with debugging

enabled.

For example:

<configuration>

<system.windows.forms jitDebugging="true" />

</configuration>

When JIT debugging is enabled, any unhandled exception

will be sent to the JIT debugger registered on the computer

rather than be handled by this dialog box.

    Hi,@Ryan Reventlow. Welcome to Microsoft Q&A. 

    From the error message, it seems that there is a problem with the database connection. You could refer to the following solutions to solve it.

    1. Check the SQL Server status: Make sure your SQL Server instance is running. You could check it using SQL Server Management Studio (SSMS) or through the Services Panel (services.msc) in Windows.
    2. Network connection: Make sure the computer can access SQL Server via ping. Check that the firewall settings on the client and server are not blocking SQL Server traffic.
    3. Make sure the connection string is correct.
    4. If you are connecting to the database remotely, make sure remote connections are enabled (in SSMS, right-click the server, go to Properties > Connections, and check Allow remote connections to this server.

    Firewall settings: Make sure the firewall on the SQL Server computer allows SQL Server to communicate on the necessary ports (default port: 1433).).

    If you could provide the minimum code and steps to reproduce the problem, I will be able to solve your problem more accurately.
