Cannot read properties of undefined (reading Datasources

When trying to edit my PowerApp I get an error message saying: "Cannot read properties of undefined (reading 'dataSources'). This is before I am entering the editor which means I am completly locked out of editing the app.

 

I have tried deleting some of my connectors, but this has not helped. The error appeared after I used an already created connector for another project that was shared with me, but where I am not the owner.

    Hi!
    I got the same problem.

    after looking at the errorcode it seems like it's because of a language problem (, = ; and so on).
    Try to go to your browser settings and change to English. then refresh and you might be able to access your app in editor. 

    I guess Microsoft is going to fix this.
