Composition window only showing wireframes
I seem to be having issues with a group of files I have been working on. It started with one, and now Im this issues with all of them. When I try to open the file, all I see are wireframes in composition window, no images (screenshot attached). When I try to preview I get the error message "Cached preview needs two or more frames to playback." And when I export to media encoder, it tends to stall and crash.
*On a side note, I AM able to view the images in the precomps. Just not in the main timeline.
The size of the working file is 6.9MB. There are also a lot of layered .psd links and around 11 precomps (not sure if that info is useful or helpful)
Computer Specs:
MAC OS High Sierra
Processor: 3.2 GHz
Memory: 8G
Graphics: AMD Radeon R9 M390 2048 MB
Software Specs:
After Effects CC 15.1.2
Media Encoder CC 12.1.2
Things I've tried:
- Restarts
- Removing and reinstalling After Effects and Media Encoder
- Checked for broken links
- Preview mode: full
- Empty Disk Cache
- Clean Database and Cache
- Set max memory to AE (6.5G to AE, 1.5 to other software)
- Composition > fit to window size
- Tried preview panel, as opposed to preview from timeline
Any thoughts on what the issue could be?
