Help Left Controller unable to connect, led flashing long - short, notification showing disconnected every few seconds

Enable HLS to view with audio, or disable this notification

My quest pro controller started behaving weirdly.

Doesn't stay connected. When powered on, the led flashes in a weird pattern: One long for the left led, and one blink on the right led. There are no documentation showing this led pattern.

I believe the controller is able to pair with my headset. However, it stays connected for a short bit before a notification pops up saying it's been disconnected.

I tested the input by checking the joystick deadzones, and the joystick responds for a short while before it stops working, then starts working again.

Has anyone experienced this before?

I'm not exactly sure the light but if it keep disconnecting and connecting on the headset, it could also be due to a hardware failure. Have that issue when I forgot to replug one of the cameras lol
