After reading NFC we have a success ringtone. Sometimes this fails, with the following error: <img width="1958" height="272" alt="Image" src="https://github.com/user-attachments/assets/d5262a9a-bb1e-4e3b-9809-c22a98c6d322" /> I think you'd have to re-validate the ringtone object on each call to see if it became null.
