Subject: Assistance Required for After Effects Error: “Unknown Exception”

Hi, 
 
I am reaching out for assistance with an issue I have been experiencing in After Effects 2024. I keep encountering an error message stating “unknown exception” whenever I click on the Effects panel, try to nest a sequence or try to apply any effects. 
 
I've taken the following troubleshooting steps:
 
1. Reset Preferences: I have reset the preferences during startup.
2. Disabled GPU Acceleration: I disabled hardware acceleration in the preferences.
3. Cleared Disk Cache: I purged all memory and disk cache.
4. Reinstalled After Effects: I uninstalled and reinstalled After Effects, excluding Cinema 4D, as I do not use it.
5. Updated Software: I ensured that After Effects and my mac software are both up to date.
 
Despite these attempts, the error persists. I would appreciate any guidance on how to resolve this issue, as it has hindered my workflow significantly today and means I am stuck until this is fixed:((
 
Thank in advance for any advise and help! 🙂
 
Best regards,
Rosanna

It sounds like you've done excellent work in trying to solve this. My last resort option when other trouble shooting options don't work is is using the Adobe Cleaning tool. It starts everything fresh but is time consuming. Here is more info: https://helpx.adobe.com/creative-cloud/kb/cc-cleaner-tool-installation-problems.html

    Thank you Rob! I will try this. Really appreciate the tip 🙂

     

    If this is useful should somebody else have this issue, although I feel a little unsure: Adobe's chat assistant has instructed me to download the Beta version of After Effects from Creative Cloud and has advised I should use this from now on. I'm a bit wary as whilst it has worked so far I understand this may have its own issues. I wonder if other people have had this with problem using the latest macOS system and AE 2024. Adobe's assistant's advice seems like a plaster over the problem 😕😕 But it allows me to work atm so this is something at the least!

    For more context, I am using:

    • After Effects 2024
    • MacBook Pro 2017 (16-inch)
    • macOS Sequoia 15
    • Graphics: AMD Radeon Pro 5500M 4 GB & Intel UHD Graphics 630 1536 MB
    • RAM: 16 GB 2667 MHz DDR4

    The test file I used was a simple PSD file with three layers, a camera, and minimal elements.

    Any help or insights would be greatly appreciated!

    Thanks, R
