AO Classic Freezing in Windows 11

Hello, all.

I have an accountant client who is experiencing freezes when they are using AO Classic on Windows 11. They're getting the following error in the Event Viewer:

Failed to get IntegrationType when send login telemetry data, error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
