Would you mind resetting the preferences and media cache manually to make the settings default? Here are the steps:

Reset media cache- 

  1. Go to C:\Users\username\AppData\Roaming\Adobe\Common
  2. Rename Common as Commonold

 

Reset preferences

  1. Go to C:\Users\username\AppData\Roaming\Adobe\After Effects
  2. Rename 17.0 as 17.0old
  3. Go to C:\Users\username\Documents\Adobe
  4. Rename After Effects as After Effectsold
  5. Restart your computer.

 

Launch After Effects and check if it brings any change.

 

Let us know.

 

Thanks,

Adobe After Effects needs to be run in Windows 8 Compatibility Mode to make it work

I had the same problem last night with 2020. It was missing the GeForce Experience and Nvidia Studio drivers.

 

I also think I had bad RAM, so if you've moved that around recently maybe take a look, see you have matching DIMMs and in the recommended slots (read the motherboard manual re. slots)

1. Right-Click the app

2. Right-Click "Adobe After Effects (year)"

3. Click "Properties"

4. Click "Compatibility"

5. Click "Run Compatibility Shooter"

6. Click "Try Recommended Settings" 

7. Click "Test the Program"

This fixed mine right away!

Let me know if it worked!!!

Thanks for trying. What happens if you leave After Effects for some time. Does it show any error message? Try disabling the Windows Defender or any other anti-virus and see if it brings any change.

Let us know.

Hi there,

 

Welcome to the community and sorry for your issue. As suggested by Mylenium, try updating the driver and installing the windows updates. Outdated drivers are one of the most common reasons for After Effects not launch properly. In addition to that, try the steps suggested in the following article: https://community.adobe.com/t5/after-effects/faq-how-to-fix-common-after-effects-crashes/td-p/10684130?page=1

Let us know how it goes.

 

Thanks,

Nishu

Start by updating your drivers, either via the Lenovo tool or Windows update.
