App becomes an image after migrating to Capacitor 4

Capacitor
1

I have my android app using Ionic 6 and Capacitor 3. I started a new version for my app so I copied all my project to a new folder. The VS Code Ionic extension recommends a migration to Capacitor 4. So I did that. But after the migration the app stopped working. When I try to debug using the following commands:

export NODE_OPTIONS=--openssl-legacy-provider
ionic cap run android -l --external

Now the app only show this image:

What it means? I have no errors nor warnings.
