    Hi @juerlin,

     

    Please first take a try with the method mentioned in the article below:

    Troubleshooting startup issues in PowerApps Web Authoring

     

    As the termination is specific issue, if you have tried the method and the issue sitll insists, then please consider create a support ticket for further assistance.

    PowerApps support

     

    Regards,

    Thanks for the hints, but still not working.

    When I am creating a new app out of the examples, the web editor works...

    Any of my own apps which worked before can't be editted anymore. I can still can  run them.

    What next ?

    Just a thought: I am creating and edditing the apps with a powerapps community plan licence. Is this maybe the issue ?
