Unable to process your request
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
If your you address does not match with Region, it will not work. Also at least one Phone Number from that region must be assigned to the account and also added to the MFA (2-factor authentication). This means you must authenticate they phone number twice.
So make sure you the region you want to create the developer account for, matches with address and phone numbers. You can have other phone numbers as well on the account from other regions, but one must be a matching one.
