Venu 2S white flickering screen, unresponsive device

Hi,

Can anyone tell me what might be wrong with my Garmin Venu 2S? This is a refurbished watch from May 2024 when I made a claim because my previous device was having similar issues. A bit before this device stopped working, I would go into the menu to try and view notifications I was getting on my phone and the watch would keep exiting really fast back to the watch face. And then the screen stopped working altogether and it flicks white and vibrates and the sensor flickers green but the screen does not work and it's unusable. Grateful for any advice, thanks in advance!.
