I am having the same issue and I have the most current version of Illustrator (23.0.03). This just started occurring with the most recent update for me. I have been searching to find a way around this and haven't been able to find one. Once I use a gradient fill , I cannot deselect the gradient sliders to change the color to a solid. Any new shape i draw is given the same gradient fill automatically.
