As per discussion:
https://github.com/orgs/micropython/discussions/12573
rshell appears to hang after 5-20 loops of the following program:

from time import sleep
from machine import lightsleep

while True:
    print ('waiting 2 seconds for a CTRL-C')
    sleep(2)
    print ('going to lightsleep for 2 seconds')
    sleep(0.1)
    lightsleep(2000)
    print ('woke-up again')
    sleep(0.1)

lightsleep messing with the USB has been suggested as a possible cause.

Assuming lightsleep is I/O-driven using USB, 70288d8 might solve your problem now.
