That issue is known and - as far as I know - they are working on it so we just have to wait paitiently for next update that is comming soon. And as for now - you just have to revert to earlier AE/AME version and use those.
And as general rule - that I learned the hard way - for all operating systems, software and even hardware i suggerst in the future not to jump on to new software or new update just as it is release - specialy if you are just removing older working perfectly version on newes shiny one during working on commercial ()or even private) project.
I highly recomend of course instal new version, test new version but if it is possible instal as a separate instance not to replace your working older software, and then work on your project on older version. The same time make a copy of your project and open it in nevest version, test run it, check if all works as it should - and only, only after being sure that new software works start your normal work there.
How did I learned that? No. Not with Adobe software. Long time ago I was working on quite big commercial project (AE/PPro) ... just in the middle of that i've got a message from operating system (Windows XP - yes... that long time ago
) that new Service Pack is ready to download and instal, serviec pack that make system more stable and faster - who would not want that. So I installed it.
Long story short ... Microsoft stopped distributing that SP and apologize for "instability issues" and I - I landed with bricked 2 computers (main computer and other used as quasi render farm), part of my files and footage errased from my hard drive. That was the result of that "instabilty issues" that MS was talking about for me. And thank od I had one other even older PC that I did not updated and thank God I had quite fresh backup of my files and onyl because of that I could - spending much longer hours and sleepless nights - finish my project and send to client just minutes before deadline.
Sorry for my long storry but I hope that my story will help and stop similar stories to happened to you. And does not matter if we are tralking about Adobe software, operating systems, other software oruntested new hardware.
