Hello Erick Javier Sánchez Gama,
Based on your description, it looks like you’re encountering error code AADSTS5000224 when trying to access the Application in your tenant. This error typically occurs when authentication for your Azure tenant has been temporarily disabled due to a recent security incident. To resolve this, we need to work with our engineering team to re-enable authentication for your tenant.
Since you’re an internal Microsoft employee, I’ve provided the specific steps to involve the engineering team, as the process differs for internal staff.
I have shared those steps to you over team's chat. Please check and let me know if you have any queries.
