Describe the bug
I haven't been able to start the module for a few days now. Error message:

Traceback (most recent call last): File "/usr/local/bin/carconnectivity-mqtt", line 5, in <module> from carconnectivity_mqtt.carconnectivity_mqtt_base import main File "/usr/local/lib/python3.11/dist-packages/carconnectivity_mqtt/carconnectivity_mqtt_base.py", line 8, in <module> from carconnectivity.carconnectivity_base import CLI File "/usr/local/lib/python3.11/dist-packages/carconnectivity/carconnectivity_base.py", line 16, in <module> from carconnectivity import carconnectivity, errors, util File "/usr/local/lib/python3.11/dist-packages/carconnectivity/carconnectivity.py", line 13, in <module> from cryptography.fernet import Fernet, InvalidToken ModuleNotFoundError: No module named 'cryptography'

• OS: Raspberry bookworm
• Version from 4.12.2025

After install it works for same days.

a python3 -m pip install --upgrade cryptography solves the problem
