Hi @markahrens2

have you checked if this is your index JS script?

What happens if you disable Launch altogether i.e., via network request blocking (right-click on the launch script in the network tab and block) and reload?

Do you still see the error?

Cheers

This error is not related to the launch script or tag manager it is related to DOM(document object model) might be because the following properties are not available to edit.
