macos – “Different…” New person has been created and it wasn’t me. (Monterey 12.4 ( 21F79))

2 days in the past once I turned on my machine I discovered this display screen:
(“Otra…”) means different in English, sorry but it surely’s all in Spanish. Once I go to verify within the dictionary utility if the foundation person is activated, I affirm that it’s not, anyway I activate it once more, I alter the password once more, and I deactivate it once more, this didn’t work, it doesn’t work both to do with the “visitor person”, I’ve already formatted your complete system and I’ve executed a clear reinstall of the working system from scratch. However the issue persists, my head begins to formulate unusual theories about an software or somebody remotely creating that person with root privileges, I learn some outdated posts about it however we’re speaking about Yosemite, by the way in which the model of the working system is: Monterey 12.4 ( 21F79)]1
I might actually recognize if somebody may information me on what is occurring on my login display screen. Ivan.
