X message “Failed to load content. Please try again.”

I just got my new iPhone 17 Pro and transferred my iPhone 12 Pro to it. I’ve downloaded and deleted X multiple times and can’t get anything to load, let alone am I able to log in. I keep getting the message “Failed to load content. Please try again” when trying to add a second account. Each time I click “reload” the same message appears. All my other apps works just fine except for this one.
