I can't use anymore Element 3D, Saber, Keylight and a lot more plugins on AE. Even when I'm opening a project using those plugins, it doesn't work and all the effects are disabled. I see an error message that say there isn't enough storage left on my disk : what's false. I don't know how to fix this, is there someone who know what I can do.
Those plug-ins have not yet been optimized to run natively on Apple Silicon. You could try running AE via Rosetta. If you are on PC, they just may not work yet with this version. Either way, best to reach out to Video Copilot and other plug-in developers for compatibility updates.
