The 2d adaptive toolpath seems to be creating a valid toolpath. What is the pin size that needs to fit in the slot?
@jeff_strater: Can you forward this to the right people?

Even though the section size you selected was 5.75mm, the width of the slot in the screen capture below shows it to be only 4.22mm about 40mm from the top. Perhaps @TrippyLighting, @HughesTooling, @SaeedHamza, or @davebYYPCU could provide a reason for this. I don't use the Coil command enough to know its idiosyncrasies.

Thanks for the mention @etfrench
What I think is wrong here is something in the process @Anonymous used, because normally this shouldn't create any problems
Here is a screencast to show who to create the coil with the desired slot size
And @etfrench try to measure the distance between both faces ( upper and lower ) using the measure tool instead of creating a line, it's more accurate

The problem is the coil command in Fusion is not very good, the profile is parallel with the axis but it needs to be perpendicular to the helix. Attached is a screencast and file that shows how to fix by rotating the end face so it's perpendicular.
I use Diameter1 and Pitch1 for the first coil then this equation with give the angle the face need to be. atan(Pitch1 / ( PI * Diameter1 ))
For some reason you can't modify the helix directly so you have to cut the coil from the shaft then rotate the face then press pull to correct the error. Probably could make parameters for this as well with a bit of effort.

Don't know if this will cause you problems but the 2 helical faces are not parallel, another problem caused by the profile not being perpendicular to the helix.

The problem is a mixture of what @HughesTooling wrote with the profile not being perpendicular to the path and sow of what has been posted in this thread about creation a barrel cam in Fusion 360. I had created a screencast but it was found not to be entirely correct. This is a non trivial solution for Fusion 360 and one of the reasons is the the amateurish implementation of the coil tool.
Try making each helix a little longer then use the split tool to remove the overlap.
