My Yeelight 10W RGB bulb turns off by itself and turns on randomly

Hi everyone

I have a Yeelight 10W RGB bulb, and lately, it has been acting very strangely: when I turn it on, it immediately shuts off by itself, and keeps doing so if I try again.Other times, it just turns on by itself without any command.I have already checked the power connection and it seems fine. Does anyone know what could be causing this issue or how to fix it?

Thanks in advance for your help!
