Graceful exit a process/threadpoolexecutor

Python Help
1

i have a process/threadpoolexecutor in a context manager, at keyboardinterrupt i want to close all threads or processes while keeping the error completely silent

in the main program i catch it and exiting, however i cant manage to silence the error in child processes

try:
    with ProcessPoolExecutor() as executor:
        # do stuff
        # then run future.result() to raise errors

except KeyboardInterrupt:
    # exit silently
    return

except Exception:
    # handle other errors

my code looks like this, i need the same thing for both thread and processes

in short the issue is that even with this, it prints the traceback from child processes receiving keyboardinterrupt, all i want is for that error to be silent from them
