I didn’t understand the encryption properly. So you have three things which are the IVs, the key, and the key stream. IV + key = key stream, so key stream – IV = key. Can we see the stream key in order to solve the equation? And why do we need a repeated IV to crack the key stream and how does it get cracked.

No the only thing that we can see in plain text is the IV, therefore when we capture lots of data the IVs start getting repeated, each revealing small bits of into that help determine the key stream.
