I'm receiving these error codes when I try to preview any files within this project. Even when I scrub through the CTI, none of the comps on the timeline are visible on the preview screen. I examined the boards on Adobe Community, and several other people have the same problem on 'Unknown BIB Error. invalid container, 0 (83:: 3)', but with no results. The "solution" to that special error code was deleting my font cache. I followed the steps, but the error code continued after that. I tried uninstalling and reinstalling After Effects to no avail. I also tried opening a new project file and importing that file, but the error code was displayed there. Due to these issues, my workflow came to a grinding halt. I'm past due on the delivery for a client waiting on this project. I've attached screen images of the multiple error codes that pop up and keep me from using After Effects.
Sorry for your issue.
I have seen these errors before but not together. Could you share your system specifications (CPU, GPU, RAM, OS version)? What's the exact version of After Effects you're using? Also, does it happen with all the projects or a particular one?
Please try resetting the After Effects preferences: https://community.adobe.com/t5/after-effects-discussions/faq-how-to-reset-trash-preferences-in-after...
Let us know how it goes.
But I've been using the same computer for the last three years and had no troubles, with AE, up until I started working on this project.
