fusion freezes whenever i try to boundary fill

[amoncada89M47]

i am trying to fill an empty volume within an object using the boundary fill function, however as soon as i press okay after assigning my tools and cells the app freezes, and most of the time i cannot exit out of the app, I have to restart my whole computer for it to close.  Are there any particular reasons for this?  I have followed along the same methods as how-to videos for the boundary fill command, but is there something I may not be doing right?
