Problem with message/hot reload: Waiting for connectivity with react-scripts

since some local updates ionic wont hot reload anymore and this message oncours:
[INFO] Waiting for connectivity with react-scripts

Does anybody knows what went wrong here. Ic just updateded everything, node, npm, ionic, still the same messge.

ionic info


   Ionic CLI       : 6.20.1 (/usr/local/lib/node_modules/@ionic/cli)
   Ionic Framework : @ionic/react 5.8.5


   Capacitor CLI      : 3.3.0
   @capacitor/android : 3.5.0
   @capacitor/core    : 3.5.0
   @capacitor/ios     : 3.5.0


   cordova-res : 0.15.4
   native-run  : 1.6.0


   NodeJS : v18.4.0 (/usr/local/Cellar/node/18.4.0/bin/node)
   npm    : 8.12.1
   OS     : macOS Monterey

I solved the problem by using Node 16 instead of node 18 (with brew).

Main problem was the missing hot reload AND an increased CPU usage.
