Titan-86L Project boring bar question

Hello, my name is Ken, I am working my way through the rocket projects and have an issue when trying to program the boring bar in the Cam/Manufacture function. I program the bore per the video, but when I run the simulation the tool holder immediately goes red and detects a crash. The error is “Rapid Collision With Stock and Holder Collides with stock”. I am using the latest version of Fusion 360 and I wonder if anyone else is having this issue. No matter what I’ve tried I can’t get the collision detection error to go away.
I also had an issue with the threading function on the Titan-84L with this software version.
