3DInterconnect tool Inventor incomplete import

I have an AD Inventor assembly that I am trying to convert to SW using the built-in 3DInterconnect tool. The original assembly is made up of multiple sub-assemblies and a few extra parts. When I open the assembly in SW it seems like SW is converting only about half the Inventor file tree and then finishes the import, there is no error message or any sign that SW ran into a problem when the import finalizes. I tried to troubleshoot by converting the Inventor file to STEP and SW opens that file correctly. Any ideas on what my issue could be? (I am using AD Inventor 2019 and SW 2019-2020)
