[Python] Exception ignored in: <function BaseMySQLSocket.__del__ at 0x000002B15E76E5E0>

I have this strange error in my code, it started to show just like that - no changes in the code.

The same code is working with no problems when I run it from pythonanywhere account, so it's something with my machine I guess. Here's the code:

mydb = mysql.connector.connect(
host='localhost',
user='root',
database='testdb'
)
mycursor = mydb.cursor()

mycursor.execute("SELECT * FROM mytable")

db_result = mycursor.fetchall()


full error:
