Recurring (every 2 seconds) Battery Charging Icon Flashing and Beep on Watch S4 post upgrade to WatchOS6

Hey - Yesterday post upgrade to OS6 for Apple Watch S4 Cellular, facing an weird issue. As far as I could remember, I have listed the steps before i noticed the issue in the watch

1. Upgraded Iphone7 to IOS13

2. Upgraded Watch S4 Cellular to OS6

3. Added Watch Face "Meridian" with Date, Weather Temp, World Clock and Noise widgets

4. While charging - it is beeping every 2 seconds (exactly same like when you connect charger and it shows charging sign)

5. This is repeating endlessly and charging probably is hampered and slowed down exponentially due to this.

6. I even tried changing the Face and tried removing the Noise widget and replaced with Heart - but issue persists even removing the face did not help

7. Apart from activating/opening the Noise app - there are no changes done to the App watch or software

I am really clueless why this should happen? Any help in this matter would be really appreciated.
