when I try to render something in After Effects (2020), at a certain point it stops and shows me this message: After effects warning: logged 4 errors, please check log. First error was "The Photoshop Library operation failed because the device has no free space". Even if I don't have Photoshop (I uninstalled it last year and this is the first time getting this error) and I have several GBs of space.
Before this, I had another error that somehow I managed to fix.
I'm using a MacBook Air, 1,6 GHz Intel Core i5, 4 RAM GB.
If your render always crashes at the same spot in the timeline, you have something going on in the comp that is using up all the system resources at that time. You may be able to split the render at that point, render the first half, then render the second half, then combine the files to complete the project.
Your computer only has 1/4 of the recommended ram. I am not surprised that you are having memory problems.
