For some reason, I can’t adjust opacity on the layer I’m working on; I can make a layer with less opacity, but whenever I turn the opacity down or up on a layer, it does nothing. When I tried to circumvent the problem by making a transparent layer and then merge it down, the resulting image had no transparency; the bits from the transparent layer were rendered completely opaque.
I tried to save my work, and it gave me the error I mentioned in my title. I checked and apparently it saved anyway, but now the background is black and only half the transparent parts exist?
I searched for this error and there was one post from 2017 that mentioned it, but it didn’t ever seem to be resolved.
