Can't render Ae project in Media Encoder, final output a still image

[MAGIKimono]

I can not figure out why this 16 second After effects file won't render in Media Encoder.  It imports into Media encoder, does a rapid encode after I click the 'start arrow' and the final output is a 00.00.00 second still .mp4

I've tried different "save as" copies. 

Other Ae projects work.

Running all current CC on Mac Pro, Mohave.

One time I got this message and thought I'd successfully kept things in the same folders.

Hi MAGIKimono,

Sorry for the trouble. It seems like an issue with this particular composition.

If possible, please share a screenshot of the Timeline panel.

Thanks,
