We had this happen several times. We changed the code many times only to find out that the builder had been using the same make and model opener over 20 years and there are not enough different codes to keep it from happening.
Solution replace a hardly used unit with a different brand.
We used Chamberlin got the top of the line with blue tooth technology.
We are part time residents so now when the door is open for service or our management company to inspect we get an alert on our phone and we can close it from anywhere using the phone app.
Good luck we tried everything we could but this was the truth haven’t had an issue since we changed it last May
