Error when importing solution

Question

Hi, 

 

I have an issue with Power Apps. I created a dev environment for an app I had in the default environment. I wanted to replace the app in the default environment with a managed solution. For that I imported a unmanaged solution in my dev environment then I used this unmanaged solution to export a managed solution. The first time I tried to import this managed solution in the Default environment I got this error :

 

Cannot add a Root Component toffice_gestiondesfichesrfrences_e2b55 of type 300 because it is not in the target system.

 

I tried again and got this error :

 

CanvasApp import: FAILURE: Code: ApplicationIdAlreadyInUse Message: The application name 'a958e8f7-7a53-4a63-b190-5475d112bb6f' in tenant 'ed0e3414-6e56-454c-8a82-eb80befb738b' is already in use. Please specify a different name. Client Request Id: 5dbb00ca-c9f0-4d04-95a3-b90a1e3014eb.

 

I also tried to import with  the old interface and got this error :

I searched for the app and it is no longer in my environment ! I don't really know how to get my solution back into my default environment. I searched the app with PowerShell and I can't find anything because I don't think I have the privilege.

I need help thank you !
