Weird noise during regenerative braking on 2022 Polestar 2

My 2022 Polestar 2 Long Range Dual Motor has started making a strange whirring or grinding noise, especially noticeable when I lift off the accelerator and the regenerative braking kicks in. It's not constant, but it's happening more frequently now, particularly at lower speeds.

I'm a bit concerned as this wasn't present when I first got the car. The braking performance itself seems okay, but the noise is definitely new and a bit unsettling. Is this a common issue with the Polestar 2's regen system, or could it indicate a more serious problem with the brakes or drivetrain?
