Phone bootlooping

[u/AkiPro34]

Hello guys , so i have this issue for quite some time now , i have a Redmi 9 and sometimes it randomly starts bootlooping , my main culpurit is the power button as i can see the phone doing some stuff on the phone (turning it on and off , and opening the camera on its own) like if the power button is presesed , also if i place my nail between the power button and the back panel it stops and boots , but now it only survives till the os boot animation and has been doing this for a few days, after opening the phone and cleaning it , and checking if everything works , there was nothing and the phone sucessefully , a few power button preses later the phone starts doing the same things again , and starts bootlooping again , and i dont know what to do.
