System Information
Operating system: Windows 10
Graphics card: NVIDIA GeForce GTX 1070Ti

Blender Version
Broken: (example: 2.80, edbf15d3c044, master, 2018-11-28, as found on the splash screen) 3.4.0 ALpha
Worked: (newest version of Blender that worked as expected) 3.3.2, 3.3.1, 3.2, 3.1

Caused by blender/blender@a8a454287a

NOTE: https://wiki.blender.org/wiki/Reference/Release_Notes/3.4/Python_API#Internal_Mesh_Format

Short description of error

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

Importing the attached FBX file throws an error only in 3.4.0 Alpha. I know its an alpha release but just though you should know.
Imports fine in earlier versions.

It seems this is a documented API change that needs to be updated. https://wiki.blender.org/wiki/Reference/Release_Notes/3.4/Python_API

@HooglyBoogly : please always check Addons for API changes.

Seems like the following is just enough (no need to enable this as a property anymore?)
