I also encountered the same error. I solved the problem by adding a new payment method in the account settings of the App Store. Maybe you can try updating the payment method. If there is a problem with the payment method, neither paid nor free apps cannot be downloaded.
The trusted phone number for 2FA has to be the same region as the Apple ID you try to enroll
