Trouble getting a toolpath to generate

[paramax55]

I'm trying to generate the toolpath for [T1] Adaptive 16 (4) - which is the last one in the tree. It gets to 5:17 machining time and stops generating. I can abort the generation and do things with the computer - it's not like the computer is frozen, it just stops progressing with the toolpath. I've tried restarting Fusion and it still stops in the same spot. I've generated 18 toolpaths on this part already, and this is the 3rd "duplicate and modify" on a toolpath that I've already cut, so I know it's not that I'm doing something completely wrong. I'm afraid that I have too many rest machining operations and the little laptop I am using can't handle it? Or maybe there is something wrong with the file I am using? Could something be corrupted?

More details... I've tried changing the top and bottom heights. I can change the top height to start in a different level and it will freeze when it gets to the same spot every time. I can raise the starting level and it will generate more toolpath code, then freeze when it reaches this corner. I can start it lower and it will generate less code, then freeze when it reaches the same corner.

So... I lowered the starting point to top -0.155. It appears that Fusion started generating an empty toolpath and froze. So it looks like Fusion gets to a certain point on this part, then starts trying to generate an empty toolpath, then freezes. Is there something wrong with my file, or is this a bug in Fusion? Do I need to export a mesh of the part after simulation, then use the mesh as my source for rest machining?

I came up with a solution, but it is not ideal. There is definitely something that Fusion does not like with this file. I ran a simulation of all the toolpaths leading up to this one, saved the stock as an STL, and used that file as my source for rest machining. It generated a toolpath that is less than ideal, but I might be able to make this work if I do some cleanup with a file afterwards. The STL looks like my stock up to this point, so that part worked out. The toolpath that was generated left out some parts that need to be cut and is also doing some extra air cutting in some other parts. The air cutting is not a big deal, but the parts that aren't cut could be something to deal with.
