My After Effects started crashing on startup

Question

My after effects was perfectly running fine yesterday. Today, one of my projects that I was working on crashed it and now the whole AE is not starting.

I updated the graphic drivers to the latest, updated windows 10 and also made sure the AE is also updated.

I even uninstalled all of CC apps and CC and used the Adobe clean up and re installed it and still not working.

I tried ALT+SHIFT+CTRL on launch and reset preferences, still the same.

The crash report mentions the below.

I have this same issue, and am also using the DisplayLink Plugable UD-3900... If anyone's found a work around please share.

Hello Everyone, I found a solution that worked for me with the UD-3900!!

I got this procedure from Microsoft: (I did have to also disable the Intel Display Adapter)

Try this:

Right click on blank desktop>select Display settings.
Scroll down and select Graphics settings.
Click on browse and select the Application .exe from program files.

For example - C:\Program Files\Adobe\Adobe After Effects CC (version number)*\After Effects.exe *Version number is whichever version you are using.

Select the app>click on options> select high performance graphic card and Click on 'save'.
Restart the computer.

Try launching AE. If this doesn't help then try the step below without changing the setting done above.

Go to Device Manager>Display adapters. Right Click on Intel and Disable it. Restart the machine and check if Intel is still disabled. If yes, launch the app and check.

I fix this bug by deleting KeenTool Plugin folder at
C:\Program Files\Adobe\Common\Plug-ins\7.0\MediaCore

So problem can be because some of your plugin.

Try to find it at crush report here
C:\Users\{Username}|\AppData\Roaming\Adobe\After Effects\24.0\logs
