Issue:

When running a toolpath in Fusion 360 Manufacturing, an exclamation mark next to the operation appears and reads "Error: Internal CAM kernel error. Please report through your support channel."

Causes:

There is an incorrect setting in the operation.

Note: This can also occur if Fusion 360 is being run on an unsupported Operating System such as Windows 7.
Windows 7 is no longer supported by Autodesk for Fusion 360

Solution:

Recreate the toolpath using the default settings in Fusion 360 (This will produce a usable toolpath without the error).
Select both the old and new toolpath.
Right-click the toolpaths.
Select compare and edit.
From there you can see the differences between the two toolpaths and isolate the variable that is causing the error.
