Why does scatter now return an error

I'm trying to use scatter in the same way I've always used it, to plot data in color, as in:
scatter(x,y, sz, dat,'filled')
where x, y and dat are m x 1 vectors and sz is just a single value (i.e. sz = 20). I get the following error:
Color must be one RGB triplet, an m-by-3 matrix of RGB triplets with one color per scatter point, or an m-by-1 vector with one value per scatter point.
This error occurs now with code I've run for years.
I recently had to reinstall Matlab due to a laptop failure and I'm using R2024b Update 2 on MacOS 15.1.1
Thanks.

It seems to work for me, though I am on R2024b no update, but otherwise the same as you.
Could you provide the input variables used in scatter that reproduce the error?
Really can be any collection of usual vectors that have always worked, but here's one:
x = 1:100;
y = sin(x);
z = x.^2;
figure
scatter(x,y,20,z,'filled')
This is the scatter function being called:
/Applications/MATLAB_R2024b.app/toolbox/matlab/graphics/graphics/scatter.m

Please show the result of
which -all height
which -all width
You would encounter the RGB error if either height or width are not the MATLAB built-in functions.

That did it. I had an old height.m in my path. Once I deleted that, scatter works again.
Thanks much!

I need to get a crystal ball toolbox license.
