Permission denied by compiling with emcc

Question

I'd like to do emcc fibonacci.c -o fibonacci.html --emrun but it occurs compile error.

emcc --version
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.64 (a1fe3902bf73a3802eae0357d273d0e37ea79898)

emcc fibonacci.c -o fibonacci.html --emrun
C:\emsdk-main\upstream\bin\llvm-objcopy.exe: error: permission denied
emcc: error: 'C:/emsdk-main/upstream/bin\llvm-objcopy.exe fibonacci.wasm fibonacci.wasm --remove-section=.debug* --remove-section=producers' failed (returned 1)

I do not understand why access to .wasm file is denied. And it cannot output .html file.

My code is below:

#include <stdio.h>
#include <emscripten.h>

int fibonacci(int n) {
    if (n <= 1) {
        return n;
    }
    return fibonacci(n - 1) + fibonacci(n - 2);
}

int main(void) {
    int n;
    printf("Enter the position of the Fibonacci number to calculate: ");
    n = emscripten_run_script_int("prompt('Enter the position of the Fibonacci number to calculate:')");

    if (n < 0) {
        printf("Invalid input. Please enter a positive number.\n");
        return 1;
    }

    int result = fibonacci(n);
    printf("The Fibonacci number at position %d is: %d\n", n, result);

    return 0;
}
