Pyodb c Ошибка: ('HY000', 'Драйвер не выдал ошибку!')

Question

У меня проблема с использованием pyodbc для подключения в MS Access

Несколько дней назад я нормально работал с моей системой, но когда я обновился, моя Anaconda начала поднимать эта ошибка.

Мой код ниже:

import pyodbc

def conn_cur_access_db(path, base):
    access_conn_str = "DRIVER=Microsoft Access Driver (*.mdb, *.accdb);DBQ={}{}".format(path,base)
    print(access_conn_str)
    conn = pyodbc.connect(access_conn_str)
    cur = conn.cursor()

    return conn, cur

path = r"G:\my\db\path"
base = "mydb.accdb"
conn, cur = conn_cur_access_db(path, base)

# do something
conn.close()
cur.close()
del conn
del cur

В моем первом соединении это работает, но когда я пытаюсь установить больше соединений, я получаю следующий Tracerback:

<ipython-input-1-827e414c3c0e> in conn_cur_access_db(path, base)
      4     access_conn_str = "DRIVER=Microsoft Access Driver (*.mdb, *.accdb);DBQ={}{}".format(path,base)
      5     print(access_conn_str)
----> 6     conn = pyodbc.connect(access_conn_str)
      7 
      8     return conn

Error: ('HY000', 'The driver did not supply an error!')

Я искал в inte rnet об этой ошибке, но я не нашел ничего о моей проблеме с MS Access

ОБНОВЛЕНИЕ

У меня есть сделал тест

for i in range(10):
    try:
        conn, cur = conn_cur_access_db(path, base)
        with conn:
            with cur:
                print("A")
                print(conn, cur)
    except Exception as e:
        print(e)
        conn, cur = conn_cur_access_db(path, base)
        with conn:
            with cur:
                print("B")
                print(conn, cur)

и результат:
