In the browser bar on the left it’s showing you this warning. The orange triangle with an exclamation mark.
When you click it it’ll likely say " some contours were discarded due to linking constraints"
This means that Fusion calculated that your lead-ins and lead outs and lead an angle and lead in radius and Pierce clearance all added up to too much to fit inside the shape you’re trying to cut.
The solution is to reduce all those values and potentially even the kerf width till fusion generates a path in those contours.
You may have to even redesign the geometry itself if it’s too small.
Click that Orange triangle and see if that’s the error it’s warning you about.
