Looks like a constant reminder of how unsecure the clipboard is. It should really be handled by the OS and treated as input that gets entered if the paste command is used (or part of the keyboard app on phones, I suppose), instead of shared memory that any app can quietly examine and/or modify.
As others mentioned, it seems like the clipboard monitor for phone numbers has crashed. I can't speak to Vivo as a brand but usually this is not nefarious just a QoL feature to allow pasting into a dialer or dial directly from clipboard pop-up when it is copied.
Does a reboot fix the issue? Seems like it's recognizing something as a phone number which isn't a phone number. A reboot might reset whatever daemon is causing the issue.
