Any help would be greatly appreciated!

I think you need to tell Fusion you have a 4th axis in the machine definitions as it’s not enabled by default. It can also produce annoyingly obtuse error messages if you try to use ‘multi-axis’ toolpaths instead of 4th axis index/wrap/etc the way it expects.

In the post processor settings, there is a dropdown field for the rotary axis. You need to select which direction the rotary is pointing in (X+/X-/Y+/Y-/None). If that field is set to none, or left blank, you will get that error.
