Error deleting Calendar Event

[studio108]

Version 9.1.2. PHP 8.0.8

I am getting the following error when trying to delete a calendar event…

Exception Occurred: /Applications/MAMP/htdocs/innovation_hubs_v912/concrete/src/Calendar/Event/EventService.php:226 Undefined property: Concrete\Core\Calendar\Event\EventService::$cID (2)

Weirdly it seems to be the second entry on the calendar that throws up the error?

When I switch to PHP 7.4 the issue no longer occurs?

Has anyone else come across this or shed some light on what might be causing the issue?
