How to fix error 127 in Geany?

Question

C++ / C#

Good evening!
When starting the program, it gives an error 127 ./geany_run_script.sh: 5: ./geany_run_script.sh: ./q: not found

#include <iostream>
#include <stdio.h>
 
using namespace std;
int main(){
    cout << "Test\n\n" << endl;
    return 0;
}

suggested to change permissions
In the terminal do: chmod +rx geany_run_script_9K6L3X.sh
Then: ./geany_run_script_9K6L3X.sh
but there is no such file geany_run_script_9K6L3X.sh.
