do you know which is the problem ?
thank you

Update the ‘Dependencies’ and try again. If not working Please share xaml or screenshot.
To Update it:

  1. Right click on first Dependencies --> Manage --> Update --> Save.

Do the same for all Dependencies.

I’ve uninstalled and re installed and it works.
