Pyodbc Error: ('HY000', 'The driver Did not Supply an error!')

Question

I’m having a little trouble using the pyodbc to connect to an MS Access.

Until a few days ago, everything was operating normally, but after updating my Anaconda, a persistent error occurred in the system.

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

In this case, it follows an excerpt from the code:

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

#nome do arquivo e diretório alterados
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

When I make the first connection, it even works, but from the second connection attempt (even having closed the connection with the database) in Tracerback has:

<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!')

I even searched the internet, but I found nothing about this error in MS Access

UPDATE

I took a test

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)

and the result:
