Assimp 5.1.4 Upgrade
Looks like Assimp went through some bugfixes recently including support for the latest blender file type (big blend changes over 2.8-2.9) this could greatly improve workflow (at least for prototyping things quickly). Hopefully some other things are ironed out now that v5.0 is more mature as there are many file type bugs. Especially when you get into the nitty gritty details of something like animation.
