Sorry, but WTF does it mean? This started happening after the update to AE 18. Could it be a third-party plugin issue or what? My project seems to work, but I haven't checked every comp in it yet, as it's quite large...
It means your hardware acceleration isn't working properly. Impossible to say more since you haven't bothered to provide any system information or other details. Start by turning off hardware acceleration in the prefs.
Sorry for not posting any system info - I have written several posts on this forum at more or less the same time and, though I've included my system info in the other ones, I indeed have forgotten to do this in this one 🙂
There it is: MacBook Pro mid-2015, Intel Iris Pro with 16GB RAM, Mac OS X 10.15.7
It also seems you are right regarding the hardware acceleration, since my other problem with AE 18 is Real-time Draft 3D not working properly It's more than likely that this is a hardware issue - but how do I fix this, if this is possible at all?
For me, the error occurs after I restart AE following a crash caused by attempting to copy layers between comps. I go one comp, copy some layers, switch to comp 2 and the app stops responding and doesn't recover. I force quit and when re-opening the project get the verifaction failure error.
We appreciate you troubleshooting the issue, sharing suggestions and implementing them too. This is the intent behind creating the community. Having said that, we're sorry for the issue. We'll look into this.
Adobe has recently released a new version of After Effects. Would you mind giving it a try?
