emrun exception thrown: NetworkError: Failed to execute 'send' on XMLHttpRequest stdio.html

I have a simple c file,
#include

int main() {
printf("Hello Word");
return 0;
}
I have compiled the file successfully to wasm with the following command:
D:\Practice\emscripten>emcc -O3 --emrun -s WASM=1 -o Hello.html hello.c

But I get an error using emrun. emrun is making an AJAX request to stdio.html. Can you please help on how to fix this issue?
