Problem with running flask on Python locally - python-3.x

Question

from flask import Flask
app = Flask(__name__)
#app.route("/")
def hello():
return "Hello World!"
when trying to run Flask in any way I have found on the internet I still get an Error
File "c:\python36\lib\socket.py", line 673, in getfqdn
hostname, aliases, ipaddrs = gethostbyaddr(name)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8a in position 5: invalid
start byte
I guess it's because there is non ascii character in my name. I tried on my other account with only ascii characters and the problem still occurs. Result is the same with with DEBUG mode. Can anyone give me some tips on this, please? The code is th official basic example from Flask's website.
D:\kiwiAdmission\flask>flask run
