I am using After Effects CC v14.0.1 on my computer with Windows 10 Home (64 bit).
I have been getting constant crashes while I am working on the project where the program will suddenly freeze and an error will occur "Application has been blocked from accessing graphics hardware".
I have try some methods
Run as administrator
Uninstall / install After Effects CC v14.0.1
Install Net 4.5
but this error still occurs.
And what graphics hardware does your system actually have? What driver version? You need to be more specific.
Tried to update your driver. Does it refer to Intel HD graphics or nVidia or AMD graphics?
This is the best way to fix this error. Then you download newer driver card, install it.
1. Open Device Manager
2. In Device Manager, you find Display Adapter and right click your display driver, click Update Driver Software option.
3. Then select Browse my computer for driver software option,
4. Now you start installing driver.
