UIGlassEffect is giving a black rectangle, I tried setting the effect directly and in the animation block, but It does not make a difference. Replacing the effect with Blur sets the effect as expected. If there is another view inside the visualeffect.contentView it's not displayed as well. I tried setting the layout constraints as well as manually setting the frame of the VisualEffectView with no luck. iOS 26.0 (23A341)
