I can't access Basic Setting Page once I added android package name and hashkey it's a blank page

I am unable to access my Facebook Developer Account to manage the app, even though the app is visible under my Meta Business Suite. Here are the details:
Business Name: Mirako Pizzerria Account: [...] I previously had full control of the app and the business account but now cannot access the Developer Dashboard. I also see a temporary block message on some actions. Please guide me on how to regain access to my developer account.

I can't access the basic settings of my app

Hi Support,
1) I cannot log in to my Mobile app using Facebook login. App ID : 551108744425196
2) Error message: App not active: This app is not currently accessible and the app developer is aware of the issue. You will be able to log in when the app is reactivated.
