Adobe Animate crashed before reaching 60% of SWF export

[fvwall]

I am trying to export a 15 second frame-by-frame animation I made in Adobe Animate CC. However, whenever I try to export the file as a movie (.swf format) it reaches about 57% before crashing. I have tried exporting on different laptops (MacBook Air and MacBook Pro), but nothing seems to help. Exporting a more primitive animation of about 2 seconds works quickly and correctly - so I really don't know whats happening.

Any help would be greatly appreciated! (Sorry if this answer is incredibly simple, I am very new to the program)

Here is the crash report:

is there anything in your library?  if so, check for a corrupt library item:

1. create a duplicate test fla (so you always preserve the original unchanged).

2. with the duplicate remove the top 1/2 of assets and test.  if there's no crash, there's likely a corrupt asset among the removed items>restore that dupcliate (or recreate it) and remove the top 1/2 of the top 1/2 (top 1/6) and test.  etc.  you should be able to narrow down the corrupt asset within n+1 steps where you have 2**n library assets.
