Getting the error as well after the monaco editor was initialized across the whole app on any input field (not the editor).
Error appears in the constructor of StandardKeyboardEvent class as Event is not a KeyboardEvent and doesn't have that method:

But it seems to be a wider issue as to why would you handle events on input fields which is not the Monaco editor?
