PyCharm 2023.2.3 Fails to Run Multiprocessing

Multiprocessing documentation gives a simple example of the use of Pool that I have broken into two separate files test.py and test_a.py

test.py is used to call the worker function in test_a.py

If I run test.py in the command line it works as expected but if I run this in PyCharm's Python Console then errors result in an endless loop until I stop the console. Below is the example code.

----------------------------------

test.py

----------------------------------

import test_a
from multiprocessing import Pool

if __name__ == '__main__':
    with Pool(5) as p:
        print(p.map(test_a.main, [1, 2, 3]))

----------------------------------

test_a.py

----------------------------------

def main(x):
    return x*x
 

----------------------------------

Errors

----------------------------------

Is there a correct configuration for this process? Or is there a fix? Or is a downgrade a possible solution? Is there any solution?
