After effects not opening a specific project (others open fine)

[Jorim5C1F]

Hi all,

I was busy editing a project using dynamic links from After Effects 18.4.1 to and from Premier Pro 15.4.1.

Im not sure what is causing it, but I think I may have created a circuler refrence.

Steps:

1. Premier pro sequence (PPS) A refrenced by PPS B
2. PPS B dynamic linked to After Effects Sequence (AES) C
3. (possible) AES B refrences PPS B (accidental, should have been PPS A, the sequence before I added the AES graphics)
4. Strange issues (playhead lag, not rendering previews)
5. Delete cache to fix
6. Crash

What's strange is that I can't open my backups either. Even opeing autosaves from before I made the refrence cause AE to hang (and display a drop shadow without a GUI box, see the attachment). Premier pro is unnefected but linked AES are offline. I can open other projects without issues.

I have deleted the cache and my prefrences, restarted AE and PP: no luck. I would very much aprreciate any ideas or help.

I would start with a backup copy of the Premiere Pro project, then start deleting any nested AE comps to see if that solves the problem. It's pretty hard to guess where the problem lies without flowcharts, project structure, and workflow details.

the attached project works fine on my iMac, so i save a new copy you can test it here

also, another solution, sometimes the font cause issue opening some project, so try to backup your fonts and remove all the third-party fonts or if you know the fonts you use in your project try to remove them and check if you can open it again
