Error when using gcc (minGW) to build .exe with same filename?

I've been trying to build another .exe file with the same name in minGW, but everytime I run the command: gcc file.c -o file.exe I run into the problem of:

c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe: 
cannot open output file main.exe: Permission denied
collect2.exe: error: ld returned 1 exit status

But, if I run the same command with gcc file.c -o file2.exe the command executes fine, and I can compile my C code. Is there any way to build .exe files with the same name?

My C code is a simple "hello world":

#include<stdio.h>

void main(){
   printf("hello world");
}

Thank you!

Updates:

• checked task manager, but the .exe is not running in the background.
