"On a test project using angular 16.x.x the most current 5.4.1 version of calendar installs and works without issue.

But on the actual project for which calendar is needed, which is fairly old v 8.2 I run into errors after installing calendar and trying to run. Once I uninstall, all goes back to normal. "
