If I can victim-blame for a moment, I don't know what my mom is supposed to do when a streaming service on her TV says there's a problem and will she please report a GUID to the support department.

No, my mom is not eidetic, and no, she's not going to upload a photo of her living room.

Totally agree with you, though, when the full error message is at least capable of being copied to the clipboard.

Most (all?) photo apps include a crop function, allowing your mom just crop out everything else.
