Is Physics broken?: Why and how can the red supergiant star Betelgeuse have a surface rotation velocity of ~49000mph, while it has a diameter that would be around the asteroid belt if concentric with Sol?

Betelgeuse is estimated to have a mass=(M>10*Sol, but M<20*Sol), and given that it started as a “type O” Blue Giant, it must have been originally rotating at a velocity that should have shredded itself.

What could have produced that initial velocity? How could Betelgeuse have initially condensed/collapsed? Is Newton’s Second Law broken, pray tell!

i feel like this could be used to turn a turbine well with wind.
