That's definitely aphantasia as I understand (and suffer from) it.

I've never really considered the "visual learning from failure" aspect of it. I know that in, e.g., Minecraft, I have tremendous trouble with building things because I can't visualise them beforehand and thus things get hodgepodged into these hideous homunculi of buildings or redstone contraptions.
