Airflow is loading plugins twice

[iJanki-gr]

Apache Airflow version

2.6.2

What happened

I'm installing a python package that contains airflow.plugins.
For some reason when I run airflow plugins the plugins show duplicated twice.
This causes an issue loading blueprints:

ValueError: The name 'edit_run_conf' is already registered for this blueprint. Use 'name=' to provide a unique name.

Plugins are definitely being loaded only from python package. The plugins_dir is empty. Verified this also with DEBUG log.

Here is how the entrypoints look like in the python package:
./venv/lib/python3.9/site-packages/gr_airflow-0.0.3.dist-info/entry_points.txt

[airflow.plugins]
cron_display_timezone_plugin = gr_airflow.plugins.timezonetrigger.plugin:CronDisplayTimezonePlugin
edit_runconf_plugin = gr_airflow.plugins.edit_runconf.plugin:EditRunConfPlugin

Any one else having this issue?

It must be something to do with python env.
I have this issue in python 3.9.2, but it seems all fine in 3.9.17

Airflow is just using the method

importlib_metadata.distributions()

So it is a python issue or something odd in my env.
