Launching program hangs if API is unavailable

Currently, if the API is unavailable, the app will hang until a 503 is returned from the server, an exception will be thrown and caught, and then the app will launch with no games.

The program should launch and display a loading screen while it waits for the API to return.

Start by locating the application launch flow and the API request that blocks startup. Check how the unavailable API and resulting 503 are handled, then identify where the loading screen should be shown while waiting. Done means the program displays a loading screen instead of hanging or launching with no games when the API is unavailable.
