Help! Loud clutch whine belt also has cracks…. (video)

Hey guys so I was out riding went through a huge puddle really slow I guess water got into belt because I lost power and it was slipping. Sat for a while in neutral and it eventually went back to normal rode the rest of the day.

Upon heading back to the truck at high speed in high was a loud whine got home took the cover off and tons of black soot on the cover and belt has some cracks on the inside and one big Crack. Also in the video it makes a loud whine. Maybe it’s clutch kit and belt time? Maybe a bearing somewhere?
