https://docs.python.org/3/library/http.server.html#http.server.SimpleHTTPRequestHandler.do_GET - "If the request was mapped to a file, it is opened. Any OSError exception in opening the requested file is mapped to a 404, 'File not found' error."

So that sounds more like a Python 3.13 bug? It should handle 404's gracefully.
