Microrosft teams Usupported Manifest Version - azure

Question

I'm developing a custom teams app and until few days ago it was running ok: wep app run local from visual studio code with chrome debug, and the service app distributed on azure.
Yesterday I deleted by mistake the local app from app studio (inside visual studio code) and then I created a new app and set it as the old.
Teams recognize the app and when I run it from local (with debug from chrome) it opens a new window on chrome and I correctly see the button for install it:
When I click install I receive one popUp error: and i can see thi erro on the local visual studio debug console:
My manifest app is a standard manifest, with 1.8 version:

}

How can I solve it?

There's currently a bug with App Studio that's being addressed (see my question here: App Studio is auto-converting my app to Schema 1.9, and the failing to install it into Teams). In the meantime, you can side-load to the internal company app store, and install from there, especially if you have a Developer tenant
