title: Angular error cannot read properties of undefined (reading 'init')
body: <p>My app was working fine but after I installed a package and now I get this Error message:</p>
  <p><a href="https://i.stack.imgur.com/XZQwR.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/XZQwR.jpg" alt="enter image description here" /></a></p>
  <p>I tried uninstalling the package, checked if any versions changed somewhere in my app. I don't know where to start with this error code, looked up several questions but none worked on my problem. I'm using Angular 7. Any ideas what can cause it?</p>
