I understand that you are receiving the AADSTS90072 error when logging in with a gmail account when trying to access the application "8c59ead7-d703-4a27-9e55-c96a0054c8d2." If you are the administrator for that tenant, I would recommend reviewing the troubleshooting steps for this error in Error AADSTS50020 - User account from identity provider does not exist in tenant . If you are not the admin, I would recommend sending your error message to your tenant administrator and referencing the article provided.
Which application are you trying to access? Could you provide screenshots of where you receive this message?
It sounds like your account has not been given access in your org/tenant or the tenant might be blocking guest users and you would need to work with your admin to get the access restored.
If your gmail account has not been added to the application in the Azure Portal, the admin can add your account directly as a guest user in the portal.
