Power Off option is popping up without the button being pressed

Not sure if this is the right forum but I'll ask anyway...

I have an issue where the Power Off option is popping up constantly on ky Galaxy Watch 3 Titanium without the button being pressed, essentially rendering the watch useless.

For a time I was still using it for activity tracking because when the screen timeout kicks in, the incessant Power Off pop up isn't an issue but then I noticed a significant increase in battery drain (Eg: Using 80% within ~ 2 hours.)

I'm about to dive in & see if I can find anything out of the ordinary; I'm thinking maybe corrosion on or around the home button pusher on the midframe but if anyone knows what is the cause of this issue &/or how to fix it, I'd be greatly appreciative.

Thank you.
