aep file won't open, stuck on "open project (not responding)"

[zythe84]

I have an After Effects file that was working totally fine earlier today, but now I cannot open the file.  When I do, it just lingers on the "Open Project" screen, shortly followed by "(not responding)".  I also cannot open any of the Auto-Save files, even the ones from yesterday in which I know the file was working fine.

The file has Dynamic Links to a Premiere Project I am working on.  I've tried opening After Effects using the Ctrl+Alt+Shift Click method to clear preferences; I've cleard the cache; copied file to new location and drive; removed MEDIA folder to try to break links.  All have the same result....

If the file is corrupt, why would the auto-save files also not be working?  This makes me wonder if there is something fishy going with the Dynamic Links...

Please help!

Some of the usual things to try:

• Restart your machine

• Create a new project and import the old project into it

• Test the project file on another machine

Hi Andrew,

Thanks for your reply!  I have tried restarting the machine, no dice.  I have also created a new file and attempted to import, no dice.

I don't have another machine to test on, but I don't believe that the file itself is corrupt, but rather there is some conflict related to the Dynamic Linking.  I think this because I was using After Effects 2019, so I thought I would try updating to 2020.  After installing, I tried opening the file and lo and behold, IT OPENED!  When doing so, it threw all kinds of warning/errors about the Dynamic Links and told me I would need to download and install Premiere 2020 as well.  So I closed it out, downloaded Premiere 2020, then tried again... Back to square one.

I'm kicking myself for not trying to save as while I had it open, but it seemed to have been resolved.  Now, I'm just trying to recreate a way of getting it open again....

It's certainly important that you have all the related software to your current AE version installed.  If you're using After Effects 2020, make sure you have Premiere Pro 2020 and Media Encoder 2020 installed as well.

Also note you can have multiple versions installed simultaneously, so make sure you have all the 2019 versions installed as well, then force it to open in the older version?  

Worth a try.

I have a mac, but I solved the problem by shutting down the "aerendercore" process. It's outrageous, but that's the way I do it and it works. You just need to wait less then a minute after closing it and then it all come back to life. 

Here's an example because it's still doing it to me...

ADOBE DO SOMETHING PLEASE

[ferdinandd55451452]

This just helped a lot, thanks!!! 

But still, this actually outrageous, sometimes i feel like every update I make, makes the CC perform worse. (And also makes me wonder why I pay for it)

[Simone Blax]

I know that feeling. But you can't do anything if these major problems begin when you almost finished your project. Still... adobe is a great product 

[default3jwpeldx6zzp]

aerendercore is not a process on my Windows 10 PC, would you or anyone reading this happen to know if there is an equivalent? Trying to save a project that has hours or work into it.

Using Adobe After Effects, Premier Pro, Audition from the cloud updated to the latest always.

AEP file is loaded in Adobe After Effects 17.7 and fails trying to load the AEP file eventually "Not Responding". A manual cancel of the process to open the AEP file closes AfterFX on screen but Task Manager shows After Effects 2020 process still running along with  supporting processes.

what is supp bro please help me

[Guido5C16]

I think they mean 'del' - bring up the task manager. 

I see that you've just posted this comment - it's happening too for me now with version 23.5 - I suspect it's a bug with the latest update, so I'm rolling back to 23.4 to see if that fixes the problem. I'll let you know

[Guido5C16]

OK, can confirm that this is a bug introduced in 23.5 as far as I can tell. I rolled back to 23.4 and it's working again.

Thank you for this solution! This worked for me as well.

Dynamic Link seems to be VERY problematic and I suspect it's related with this problem. I'll be avoiding using it between Premiere Pro and After Effects in the future.
