I'm new to Blender and I was painting the texture of my model but I accidentally clicked on F mask brush and now I can't paint anymore. I do not know how to remove this I tried to restart Blender but it doesn't work.
Also when I start a new file it said that "Missing Data" something about texture slots.
edit: I have this brush selected.
edit2: the first three are of the brush I want to paint, the other three are of the F Mask brush
