How to fix 'RuntimeError: input(): lost sys.stdin' error in python 3.7

Question

I am practicing some codes and seemingly out of nowhere i have got this error when I ran a very usual piece of code. The problem i am solving takes input, calculates something and gives an output.

I was running it on an online IDE (some coding contest site) and since it wasn't very good(no surprises there!) i decided to run it on the Pycharm Community Edition and then copy paste it over there. Instead of giving me an output, it showed this,

Traceback (most recent call last):
  File "D:\Software\lib\io.py", line 52, in <module>
  File "D:\practice\abc.py", line 1, in <module>
RuntimeError: input(): lost sys.stdin

Process finished with exit code -1073740791 (0xC0000409)

the code i tried to run was this,

tc = int(input())
while tc > 0:
    c = 0
    a = int(input())

    while a > 0:
        print(a % 2)
        if (a % 2 == 0):
            a = a // 2
            c += a
    print(c, "is c")

    tc -= 1

this may or may not be helpful, but i don't know what's wrong.

The problem could relate to your code editor / Python window. The QGIS Python console, for example, doesn't have stdin or stdout, so you would get the 'RuntimeError: input(): lost sys.stdin' error if running your code there.
