my series 6 watch is not charging anymore and its charger works fine with other watches,what could be the likely problem.

This could be a software issue. Like we had a few years ago with the iPhone 7’s I believe it was. My wife is currently having the same issue with her watch and weather and water damage are possibilities. Also if you have kids like us, sometimes our kids like to mess with things and get curious. But I’m still looking into but could use any feedback.
