Apple Pencil gen 2 not connecting to iPad Pro 4th gen

I tried everything reset, restart, Bluetooth refresh, disconnected all app and update my software but still my iPad cannot detect my Apple Pencil. But when I tried to connect my apple pen gen 2 to an iPad Air it does connect and charge. Any suggestion what can I do to troubleshoot

Edit: I had this pen a year now. It works perfectly (connects immediately and charges ) but during this holiday break I don’t know why it doesn’t work to my iPad anymore
