stop_listening() and exceptions do not stop listening

from sshkeyboard import listen_keyboard, stop_listening

class StopException(Exception):
    pass

def keypress(key):
    if key == 's':
        #  stop_listening()
        raise StopException()
    print(key)

while True:
    print('listening from now')
    try:
        listen_keyboard(on_press=keypress, until='enter', sequential=True, delay_second_char=0, delay_other_chars=0)
    except StopException:
        #  stop_listening()
        print('listening requested to be stopped')

As soon as s is pressed for the first time and the loop reiterates, I am getting an AssertionError: Only one listener allowed at a time. It doesn't matter which of or even if both of the stop_listening() calls are uncommented.

In the first place, I would expect an exception to stop the listening anyway.

But I am even manually requesting stop_listening(), yet listen_keyboard cannot be called again because somehow it thinks that it is already listening.
