[Debian 13] Segmentation fault on attempt to obtain a connection

[vdmitrienko]

After the release of Debian 13, we began to experience a segmentation fault on attempt to obtain a connection:

    conn_params = {
        'DRIVER': driver,
        'ADDRESS': url,
        'autocommit': True,
    }
    conn = connect(**conn_params)

Fatal Python error: Segmentation fault
