Hello,
I am trying to import an FBX from a rig that uses multiple morph targets and bones into FaceFX Studio 2018.1 from Maya 2020, but the importer gets to 5% and then fails. Here is the log file text from the import:

Please send us the file
The fbx is too large to link here is there another way to send the file? I forgot to mention, the fbx does work correctly when it is re-opened back in maya if that is helpful.

I can work around the issue by unchecking the "Use FBX bind pose" checkbox on the Plugins->FBX Importer Options dialog. When this button is not checked, we assume the bind pose is at frame 0.
I imagine there is some problem with how the bind pose is stored that is causing export to fail. It's possible I will be able to fix it and use the fbx bind pose, but I will make sure that FaceFX 2020 at least detects the problem and gives a more useful error or automatically uses frame 0 as the bind pose.
I was able to fix this issue, so it will be fixed in 2020. The FBX file had invalid skin clusters that are now skipped correctly. If you need to use the FBX bind pose, I can provide the FaceFX 2020 FBX exporter toolchain for you to use with FaceFX 2018.
