Why is my global list not getting appended in Python when using multiprocessing?

When I run my code the global list stays empty, even though it should get the entries.
The test doesn't get appended, is it likely due to multi processing?

import multiprocessing
import os
import time

uncounted = []
test = [{'id': 'UC8YCf2zyqY8E7-CCOnr_kQA', 'name': 'dominic alting:('}, {'id': 'UCxm1n3Hil3l9mmPWcONd4Dg', 'name': 'Toes Jr.'}]

dir_path = "./json/"
i = 0
xi = -1


def load(pathD):
    pathD = test
    global uncounted
    return pathD


def multiprocessing_func(dp):
    global uncounted
    time.sleep(2)
    u = load(dp)
    uncounted.append(u)


errors = []


def main(xi):
    if __name__ == '__main__':
        starttime = time.time()
        processes = []
        for i in range(0, 10):
            print(f'{i} has started')
            i += 1
            xi += 1
            try:
                p = multiprocessing.Process(
                    target=multiprocessing_func, args=(os.listdir(dir_path)[xi],))
                processes.append(p)
                p.start()
            except:
                errors.append(i)
                print(f"{i} - no more path")

        for process in processes:
            process.join()
        print('That took {} seconds'.format(time.time() - starttime))
        print(uncounted)

main(xi)

Tried appending without global but then I get the same outcome

The function, that changes the list, isn't running, because there is no file. This must be always reviewed.
