Dynamic Link AE comps are "Pending"

This is horribly infuriating.

I have a project with a lot of dynamic linked comps in the timelines.  I have 10 hour long sequences that reference the same AE  project.  In 2 of my sequences, despite being online in the bin, I have the yellow "Media Pending" in my program monitor.  I have tried EVERYTHING I can find.  Trashing preferences, resetting Premiere, changing permissions, epty the cache, etc.  Everything!  I can't redo them because the info I need was delivered to me as Dropbox comments and the file is no longer available nor the person who made the comments.  I have even tried this in the new 2020 version.

Why would some of the roughly 100 instances of this AE project stop working?  I have already missed the deadline and if I can't figure this out yesterday, I'm probably not going the get paid.  I don't know why I keep paying for somethign that doesn't work.  I need and asnwer now!

This is happening across 2 computers.  An iMac and Macbook Pro, both running Premiere 2019 and Mojave.
