Content Aware Fill error "Content-Aware Fill Error: Initialization Failed"

Hi @Tom5E0F,

Thank you for reporting this issue. We unfortunately aren't able to reproduce the same error/failure when using Content-Aware Fill on our in-house macOS test systems.

When CAF starts, it first will analyze the composition before rendering fill frames. This is indicated by the text above the progress at the bottom of the CAF panel. Does the error show up for you at the start of the Analysis phase or later on during the Rendering phase?

Is it possible that permissions on your external SSD are preventing the CAF from creating the rendered Fill frames? By default, CAF renders these frames in a "Fills" folder next to your project file. If this folder can't be created, it would cause CAF to fail. Try explicitly setting the destination for fill frames to somewhere on your local hard disk by going to "Content-Aware Fill Settings..." in the hamburger menu of the CAF panel, then changing Output Location from "Project Relative" to "Absolute" and choosing a path on your local drive.

Thanks again for reporting this issue and for any further information you can provide,
