Checklist Source Error

• Use the example parameters for your source (often available in the documentation) (don't forget to restart Home Assistant after changing the configuration)
• Checked that the website of your service provider is still working
• Tested my attributes on the service provider website (if possible)
• I have tested with the latest version of the integration (master) (for HACS in the 3 dot menu of the integration click on "Redownload" and choose master as version)

Checklist Sensor Error

• Checked in the Home Assistant Calendar tab if the event names match the types names (if types argument is used)

Required

• I have searched past (closed AND opened) issues to see if this bug has already been reported, and it hasn't been.
• I understand that people give their precious time for free, and thus I've done my very best to make this problem as easy as possible to investigate.

[Gloomyeye]

I can confirm that this bug is introduced with the newest 2025.1 beta version.

I also have this bug in 2025.1 beta.

Could it be that Python version 3.13 is the sources of the error. https://rc.home-assistant.io/blog/2024/12/04/release-202412/#weve-upgraded-to-python-313 I also found. https://rc.home-assistant.io/changelogs/core-2025.1 _Look her for: Ensure icalendar==6.1.0 is installed for caldav integration. home-assistant/core#133541
