yup personally I don't know anybody who have got that when training and what I have heard it is usually not enough water + some sketchy supplements like https://en.wikipedia.org/wiki/Hydroxycut .

What does creatine have to do with it? If anything, creatine seems to reduce the risk, by reducing the amount of muscle damage:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5371628/#:~:tex....

"Overall, the available data strongly suggest that creatine supplementation prior to an endurance exercise challenge reduces muscle damage and inflammation in athletes, both of which would predict a lower risk of rhabdomyolysis, not a higher risk."

Creatine gives you extra strength which could allow you to push your muscles harder.

Creatine is processed by the kidneys, which exacerbated or caused the rhabdo. The kidneys were too stressed to handle the muscle breakdown.
