Cinema 4D Not working in After Effects and Crashing It

[Brandon Loshe]

Hello Adobe Community,

Recently, I updated After Effects from Version 24.1 to 24.3. Now After Effects crashes any time I try to use Cinema 4D (a .c4d file). If I try to import a .c4d file, AE will crash. If I try to open a project with a .c4d file already in it, it will crash. I have some AE compositions dynamically linked in my Premiere Pro sequence. Premiere Pro is unable to export because of this, too. I tried rolling back After Effects and Premiere Pro to 24.1, but the problem is still here. Updating After Effects to 24.4 made no difference, either. I can open the Cinema 4D file perfectly fine within Cinema 4D. Adobe Support was able to open my After Effects project without a problem. So it's something strange on my computer.

So far, none of these work:

-Uninstall and reinstall the apps

-Removing 3rd party plug-ins (it's a Cinema 4D issue anyway)

-Adobe Creative Cloud Cleaner Tool (and reintall)

-Give all Adobe folders and app full disk permissions

OS Details:

-Edition Windows 11 Pro
-Version 23H2
-OS build 22631.3447

Anyone else experience this? Any additional ideas for me to try troubleshooting this?

Maybe you could also ask Maxon to see if they have a suggestion.

Not a bad idea. I could perhaps try that. But the .c4d file plays back perfectly fine in Cinema 4D. So I suspect that Maxon will point their finger at Adobe (which I still feel is an After Effects problem).

I started experiencing this after updated my graphics card to the NVIDIA RTX 4090. NVIDIA replaced the graphics card and I worked with Adobe's support for a bit - tried pretty much every possible solution online too - but no solution has ever been found. Fortunately I mostly work in 2D but I've been having this issue for a year and it's definitly crippling my workflow.
