No longer showing image/preview

[RavenSK]

I've been working on this for hours, was able to view every single layer, used the puppet tool/keyframes on multiple layers, previewed the composition, etc.

Then it suddenly decided to go completely invisible. When I click a layer I see the white boxes of where it is, but not the actual image. When I try to preview it says it can't get 2 cached images. I can click the layers in the "project" section and it shows the small image of it, but won't show on the primary viewer.

I have tried purging the memory/cache, restarting the program, restarting my computer, don't have any GPU updates, none of it works. I've tried checking/rechecking every box in the preview section,  tried checking/unchecking "preserve framerate/resolution" in comp setting. There is no audio in this file, only images, but I still tried right clicking and unchecking the "audio" selection for preview. I can open the orignal PSD file (as if I'm starting it over) and it shows the iamges, but it doesn't show them on my actual animation file.

Please help.

Would you try to turn off the option of "Enable Multi-Frame Rendering" in Preferences > Memory & Performance tab if you use  a third-party plug-in?

I don't use any plugins (that I'm aware of? Unless Adobe has default ones)
I tried that regardless and it doesn't work.
