[Vue warn]: Invalid VNode type: Symbol(v-fgt) (symbol)

I upgraded the package to the latest version from "2.4.1" and I am getting the following error:

runtime-core.esm-bundler.js:40 [Vue warn]: Invalid VNode type: Symbol(v-fgt) (symbol) 
  at <AVWaveform src="http://foo.com/music.ogg" >

  at <AppMessaging onVnodeUnmounted=fn<onVnodeUnmounted> ref=Ref< Proxy(Object) {…} > > 
  at <RouterView> 
  at <PrivateLayout key=1 > 
  at <App>

I followed the install instructions but that didn't fix it.

Any way to fix it?
