With the update released this week for Premiere Pro CC 2019 (13.0.2) and After Effects CC 2019 (16.0.2), I can't open either. Premiere Pro stops at the loading screen when loading "WebM" and shows the "could not find any capable video play modules" warning and closes. After Effects crashes when loading "MediaCore". The very previous version of each one (still CC 2019) still works for me. I contacted Adobe Chat support, but the issue was left unresolved and they theorized it was an OS issue. I've read online at least three people with the very same issue, but not luck. All the drivers are up to date. All the other CC stuff I have installed still works, including Media Encoder.
