When I run this code on Python 3.11 it runs fine, but if I import typing_minimal (or typing) in reader.py I get this error:
Fatal Python error: _enter_buffered_busy: could not acquire lock for <_io.BufferedReader name='<stdin>'> at interpreter shutdown, possibly due to daemon threadsPython runtime state: finalizing (tstate=0x00007fff13ab6960)Current thread 0x00003944 (most recent call first):<no Python frame>main.py:

I'm very confused.
