The company is secretly recruiting my current position for no reason, admitting that I am not my reason, but looking for someone with considerable experience to take her.

In doing so, the company has been looking for a spare tire, and its attitude has always been clear. It's not your fault, it's just comforting words. They are worried that you will leave without help.

If I were you, I would start looking for new job opportunities and give myself more choices. Let the company speak first, and then leave with severance pay to find a new job. You are not easy to find, they are not easy to recruit and toss, but at this point, prepare to jump ship.
