 I'm not sure of what information of the project I should share for help but here's some.

-it's an edit containing 1 video and 7 images. The whole video lasts for about 11 seconds

-element 3d involved, used the displace effect on a sphere

-it was about the 7.6 second mark that gave me this notice

-i use mac catalina ver 10.15.6 

-Intel Core i7

-i use Adobe After Effects 2020 version 18.0.1 (i think) (Just the newest version by now)

-my composition size is 900 x 900

-i mostly used simple transitions such as masks and scale and rotation

-i used 3 null layers

-i'm on 8 bit and 30fps

-i precomposed all the layers together

Please tell me if I need to provide any more information. I would gladly do so. I've been trying to render my project for at least 13 times but it all went in vein. It would be nice if someone helped, thanks. Have a brilliant day.

-p.s. Forgot to mention that this is my first time using After Effects.

Probably it is because you have some elements on a very big size and you have reached the limits of AE. Check your still images. Try to change the size or resolution to a smaller size (using photoshop) to avoid that problem

I don't have photoshop though
