Updated from what version to 13.2?
See if that helps.
If not, provide as much info as you can: FAQ: What information should I provide ?
It auto updated through the creative cloud updater, I assume 13.1## . I always let it update when it says available. And I tried that post and all the others that speak to hanging on start or hanging on mediacore load. I have not added any third party quicktime apps codecs or players.
If it was a new update that came through just the other day, it wasn't an update to AE at all; it was simply an Adobe Camera RAW update. It shows as AE updating because AE uses camera RAW, but it wasn't actually an AE update.
In any case, that is unlikely to have caused the problem.
Try reverting to your older graphics driver.
How do I get a more detailed log from after effects to see what is causing error? Also, thanks for being so responsive.
I don't know. If you can't open any CC product, it's probably not an issue with just AE.
If rolling the graphics driver back doesn't work, you may have to uninstall, run CC Cleaner again, and reinstall.
