I've tried everything -- using software only render instead of GPU, reverting to old versions, saving the project in a different location, removing the Lumetri effects -- the render FAILS every single time. All of my adobe products are up to date with the most recent versions as of right now. I've also tried exporting as a different file and exporting in AE only and when I do the AE only AE crashes immediately lol.
A corrupted effect or even corrupted media file could cause this issue. What do you have at frame 12? If removing the effects didn't help, try removing/replacing the media for testing. It'll help to narrow down the issue.
