About half of my older projects open, some hang around 99%. It's been doing this for me for a few versions. If Premiere is the root, I'll just uninstall it. I only ever use it to make templates for other people. Personally I use Resolve as it's a billion times better. That said, a quick fix that has always worked in AE is to import the project into a blank project vs opening it. It's a total PITA though, but it'll get you out of a bind. Also, I'm on macOS, so this is a universal issue. Edit: Deleted Premiere. Still does it. Updated to 25.3.2. Still does it. I would like, for just one time in my career, to not have to deal with some super annoying bug in After Effects. Edit 2: As I was suspecting, it has to do with what workspace a project was saved in in some manner. I don't know why or what. I know that in the past if I had a script open while I was developing and then I moved it or something it would cause AE to crash on open if that script had been open. Well, it looks like something like that is still in there because as soon as I opened AE, switched to my older layout, and then closed AE and opened a file that was hanging on open, it opened fine without issue. Please fix this.
