What if Shoigu was playing Prigozhin all along?

Shoigu had certain people in the MoD encourage Prigozhin's ire, support Prig. in words. Then tell Prig. that if he makes the first move, they'll follow through. Obv. they do not. Prig. is left high and dry.

The rivalry between Shoigu and Prigozhin is well known.

If Shoigu convinced Prigozhin that Prig. had insiders willing to mutiny against Shoigu, but those insiders didn't actually exist... that is the best explanation I've pulled out of my ass, yet.
