That's a prretty small scren grab for diagnostic use. I can't make out the layer names & such. Only one question I have at the moment: what's in layers 1 through 28?
I have a couple of questions. Did you import your Illustrator file as a composition retaining layer sizes or are all of those layers separate .ai files?
Here's another question: What happens if you solo a layer? How about purge all caches? What is your fast previews setting?
Hi Rick, thank you for your reply.
I imported my illustrator file as a composition retaining layer size. However, I keep on updating and adding more layers in the illustrator file, so everytime I added a new layer in Illustrator, I imported it as a Footoage > Layer Options > Choose Layers and that's when I added the new layers from Illustrator to AE.
Nothing happened when I solo a layer and purged all caches. The following is my fast previews setting
Try starting a new composition and import your new AI file as a comp. See if your comp works then.
It's not usually a very good idea to add layers to an existing Illustrator document imported as a comp. I'd start a new AI file for your new assets.
Also, in your second screenshot I see a whole bunch of layers extending outside the comp boundary. This brings up a question about the canvas size in AI. Objects outside the canvas are cropped to the artboard so I must ask, did you change the artboard size?
I also see that you have not turned on transparency grid. What happens if you do that.
One last question about this asset
According to the info palette this layer is 1 X 1 pixel. That's a pretty useless layer size in a comp. If the middle bar layer isn't positioned precisely on the pixel grid then you'll end up with something that looks like this (the light tan - Note the position and the anchor point) :
Notice what happens when I try and line up a one pixel high (or wide or both) illustrator layer with the pixel grid as compared with a 1 X 1 white solid.
There's a bug in AE that causes odd number of pixel wide or high vector objects to be interpreted just slightly bigger. Note the anchor point in the previous example (0.8, 0.8). This tells you that AE is interpreting the layer size as 1.6 pixels by 1.6 pixels. That means nothing is going to line up ever. If you really intend your design to have a 1 pixel by any dimension shape and have it line up you must create that shape .7 points in AI. AE will interpret it as 2 pixels high or wide but it will display as one pixel and you will be able to line it up with the pixel grid....
I'm assuming that you already know about fixing the anchor point of odd sized layers so that they line up on the pixel grid. This is critical when creating very fine lines and detail that you want to use in a design. For example, if you had a shape layer that was 1 pixel by 1 pixel the anchor point would default to 0.5, 0.5 so you would have to change that to 0,0 or 1,1 to get the shape to line up on the pixel grid.
I still don't know why your project went black. Maybe there is a problem with a single new layer you created. Maybe there is a problem with a bunch of 1 X 1 pixel layers.
By the way, I thought I should mention that if you convert your vector layer to a path you will get a path that is exactly 1 pixel by 1 pixel but position of the path will have to be adjusted to get it to line up with the pixel grid. The lesson here is that if you really want to use very thin lines in a design then you should use the shape tools.

Empty your cache in AE. Then restart your computer and open after Effects. Should be back to normal.
Thanks! That was really helpful!
