DJI Mavic Pro 2 - Final Render NOT Playing

[defaultq0x15w1bhqjq]

Hello,

I have mix of DJI Pocket 2, Mavic Pro 2 clips for a video I am putting together.  Both shot at 30FPS in 4K.  The Pocket 2 video looks great and plays back perfectly when exported, however the Mavic Pro 2 clips freeze roughly on the first frame.

I have cleared my Media Cache and also Nested all of the video clips....nothing seems to be working.  I am exporting out 

Thoughts on how to fix?  It's brought my project to a complete standstill.

Anyone have any ideas on how to fix this issue?  I'm still stuck.
