Error after upgrading to Release 2023.4.5 - Protocol Buffers Error?

[Christopher Dopp]

After upgrading to 2023.4.5 I am getting the following error in my home-assistant.log file.

TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

More information: https://developers.google.com/protocol-buffers/docs/news/2022-05-06#python-updates

Prior to this it has been working without issue. I have not changed my gtfs_rt configuration at all. I just noticed that sensors that normally are populated with realtime data do not exist.

Following the link at the bottom of the message indicates changes with Python Updates of Protocol Buffers.

I switched to the latest release on the ha-gtfs-rt-v2 fork and my gtfs feeds are working again without any exceptions in the homeassistant.log file.
