Widget not displayed on Home Screen

Hi,

I'm working with WidgetKit and I have a very weird issue.

I've added a WidgetExtension Target to my existing project, then without any modification of the widget view,I cannot see it on the home screen when running the extension scheme.

I've created a new project from Xcode 11.5 then migrated to 12.0 to add the extension, and, a newly created project from Xcode 12.0 with an added extension after, and, both are working ...

What it could means ? PBXProj corrupted ? Runtime Errors on the Container App ? Misconfiguration of the Widget ?

Any helps would be appreciated =)
