This error prevents me from previewing in AE and immediately stops playback. It seems to occur with certain compositions, and will go away if they are disabled. I'm thinking it has to do with Illustrator files as it seems to occur whenever I'm using them. I am under a time crunch and dealing with this error has been extremely frustrating, especially since (according to other threads) there is no universal fix for it.
Things I've tried:
- switching Mercury Software Only to CUDA (and vice versa)
- updating gpu drivers
- reinstalling AE
- purging all memory & disk cache
- rebooting my pc
- disabling fonts in Creative Cloud (some speculated the error has to do with fonts)
The only progress I've made is by "saving as" a new project, which sometimes fixes the error and other times does not. Any suggestions are welcome! I'm willing to try anything.
My PC specs:
Processor: Intel(R) Core(TM) i7-5820K CPU @ 3.30GHz 3.30 GHz
RAM: 64 GB
GPU: NVIDIA GeForce GTX 970
Re-save your AI files with GPU previews turned off over there.
Hello, I'm a person who has the same problem
I even turned off the gpu previews, but how do I save the ai file again? Save as or overwrite with a different name?
Fantastic, worked for me.
This also worked for me! Thank you.
