Can have+V3 and Must have+V3

Would you mind if you explained the difference between can/can't have+V3 and must/mustn't have+V3?

Are they the same structure? Why?

Thanks in advance.

Myprofe, no need to get shirty just because someone doesn't understand your point. It would have been more helpful to explain to them the reason why you made the change.

Would you mind if you explained- this means would you object if you were to explain....

Would you mind explaining - this is a polite request to explain
