Looks like you are missing the Symbols...you have to download Symbols in VS Code, press Shift+Control+P to open Command Palette and then write AL>Download Symbols.
I think your configuration might be incorrect.
Double check your instance name (Business Central Administration) and the authentication method (Windows, UserName, NavUserPassword).
The port is also important, and you'll need to enable the developer service endpoint.

Could not download symbols. Please see the Visual Studio Code output log for more details.
And what does the output log say?
i want just do setting in vs code so that i will start my first extension development.
can also try to change the runtime version to 3.0 (it works for me)
