keeps show this error , my display card is 4060ti 8G ram win11，python3.10

Start at demo_gradio.py line 400, where block.launch is called, and reproduce the startup on Windows 11 with Python 3.10 and the reported RTX 4060 Ti setup. Inspect the failing /gradio_api/startup-events request and its surrounding launch path; done means the app starts without returning HTTP 503.
