Navigation triggered outside Angular zone, did you forget to call ‘’?

My app crashes (not always that’s strange) suddenly after I click on an link on my sliding ion-menu.
Everything worked before. I think it has to do with my latest update.
I could not find out what causes this error. Once the error is there it’s always there.

The next page after the click on the ion-menu link crashes, because the form-controls of the form are not available anymore. But everything is there and it worked before.
