Python 'locale.getlocale()' gives 'unknown locale error'

• Python 3.9.12 (32bit)
• Windows 10 (32bit)

When I tried getting a datetime object I get an error like below.

import datetime

dt_str = "2022-09-13 14:23:10"
dt = datetime.datetime.strptime(dt_str, "%Y-%m-%d %H:%M:%S")

"""
Traceback (most recent call last):
  File "_strptime.py", line 268, in <module>
  File "_strptime.py", line 182, in __init__
  File "_strptime.py", line 69, in __init__
  File "_strptime.py", line 28, in _getlang
  File "locale.py", line 593, in getlocale
  File "locale.py", line 501, in _parse_localename
ValueError
: 
unknown locale: ko-KR
"""

So I tried again to check out the current locale, but the same error occurred.

import locale
print(locale.getlocale())

"""

  File "locale.py", line 593, in getlocale
  File "locale.py", line 501, in _parse_localename

What is wrong with it?
