Problem solving about Unity's button event response error triggering UI events

I found an inexplicable bug when testing the project. It is obvious that the button is not bound to an event, but some buttons can trigger the UI again after clicking the UI.
After many experiments and debugging, it was finally found that there is a navigation function in the EventSystem module of the UI that will be automatically checked, and the function needs to be unchecked.

It should be noted that even if it has been unchecked, there is a chance that it will be automatically checked again by the system after restarting the project or having a freeze.
This function can be dynamically turned off when the program starts;
