That's not even close to an adequate description of the problem.
Basically, you've just called an auto repair shop and said, "My vehicle is making a funny noise. Can you fix it?"
What GPU do you have?
What, exact, version of AE are you using?
What third-party plugins and scripts do you have installed?
What OS are you using?
Basically, what Dave said - we need more info.
I have a NVIDIA GeForce GT 740 GPU.
I'm using Adobe After Effects CC 2017. (Version 18.104.22.168)
The only third-party plugin I have installed is Twixtor.
I am using windows 7. I apologize for not giving the proper amount of information, I have never posted to a forum before. Please let me know if you need anything else.
What driver are you using for your GPU? There have been some odd issues with the latest one. So, if you are on the very latest, you might consider rolling back three or four versions.
fb, are you still crashing? Need help still? Please let us know!
