The library we're using for calendar generation ( eluceo/ical → ) isn't on it's latest version and probably isn't currently supported. This should be pumped to the latest (0.16.1) for a stable release.
* Actually I read on 0.16.0 release notes that PHP 7.0 support has been dropped.
** Also 0.16.1 release notes mention PHP 8.0 support.
