There are many reasons that you can experience clicks and pops in your DAW but after I went thru all the common causes I could think of I finally came across an Antares article where it tells you the tracking function on Autotune Pro could be responsible. I never found it in any forums where anyone talks about this just there so I wanted to share! This is also a valuable lesson on making sure you read up on all the functions of your plug ins and manuals! If you're like me and didn't do that then :FACEPALM: I hope this video is helpful!
