Dualsense controller orange blinking 3 times

Hello !

First, sorry for my language, I'm french ^^

I have a ps5 and the controller give me some problems…

when i press the playstation button, it blinks 3 times in orange, but does not connect to the ps5…

I try to connect with the usb c cable directly to the ps5, but same problem… 3 orange blink…

I also connect the controller to my bacbook, and launch the “gamepad tester” website, but the controller is not recognized…

Is someone already have this problem? And know what problem could it be?

Thanks a lot for your answers, and still sorry for my English 😅
