there is a bug in the gradient tool in PS 2025 - when using it on a mask of a clipped adjustment when there is more than one adjustment layer it gives an error:
1. create a eg curves adjust layer, then create another
2. Clip both to a pixel layer below
3. attempt to use gradient tool on the topmosts layer mask
