[Avid-L2] Importing Sony files in 2019.12

Ive got 2019.12 installed and DP is dropping off media for first project.  Shot on Sony camera.  But Avid won't AMA and import only crashes system.   What codec is not here that I need.  The esoteric and complicated Sony codec site does not really help.  Im downloading what I can and trying but still no luck.

What am I missing here?

Thanks
