please provide the code block that causes this

[kumarunster]

my code just importing pandas:

...
import pandas as pd
...

and as in log visible at /usr/local/lib/python3.12/site-packages/pandas/compat/_optional.py line 132

I am also seeing this message in the homeassistant log.
Looks like it just fires once after a restart of homeassistant.
first message in log after restart:
2025-02-27 04:13:11.992 WARNING (SyncWorker_0) [homeassistant.loader] We found a custom integration pyscript which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant

then 10 minutes later , which I guess is how long it blocks for:

The pandas module import works fine (eventually?)
import pandas as pd
