windows_to_olson issues

The problem

Updating to Core 2025.1.0, I noticed the following error related to an external integration. I'm unsure if this issue is genuinely tied to the external app or possibly connected to the Calendar (hence why I'm starting this thread). However, I resolved the problem "windows_to_olson" modifying /usr/local/lib/python3.13/site-packages/icalevents/icalparser.py of package icalevents replacing "from icalendar.windows_to_olson import WINDOWS_TO_OLSON" to "from icalendar.timezone.windows_to_olson import WINDOWS_TO_OLSON".

Questo errore ha avuto origine da un'integrazione personalizzata.

This is related to a problem with the icalevents python library, see https://github.com/jazzband/icalevents/pull/145/files with the fix that is available sind 3 month, but not merged yet :-(

I've successfully tested it and it works for me now.

Using HAOS I can see no ICalEvents integration or smiliar. ICS Calendar integration already using ICalender 6.1:
"requirements": ["icalendar~=6.1","python-dateutil>=2.9.0.post0","pytz>=2024.1","recurring_ical_events~=3.3,>=3.3.4","ics>=0.7.2","arrow","httpx_auth>=0.22.0"],
