fplot and quiver return "Error using box"

Hello,
I keep getting this error when using the fplot and quiver functions, even when using the most simple example from the documentation.
fplot(@(x) sin(x))
Error using box
Too many input arguments.
Error in fplot (line 169)
box(cax,'on');
[X,Y] = meshgrid(0:6,0:6);
U = 0.25*X;
V = 0.5*Y;
quiver(X,Y,U,V,0)
Error using box
Too many input arguments.
Error in quiver (line 96)
box(cax,'on');
I have updated MATLAB and have been scouring the internet for answers. I am running macOS Sonoma. Has anyone run into these issue before?

See if you have something else in your MATLAB search path named ‘box’.
which box -all
That is the only thing I can think of that would throw that error.
Running it here:
which box -all
/MATLAB/toolbox/matlab/graph2d/box.m
If anything else show up, that could be the problem.

Thanks!
This is what I have:
>> which box -all
/Users/mathildeplacek/cobratoolbox/papers/2023_BarrierRound/3isotropic/PolytopeSamplerMatlab-develop/coverage/problems/basic/box.m
/Users/mathildeplacek/cobratoolbox/external/analysis/PolytopeSamplerMatlab/coverage/problems/basic/box.m % Shadowed
/Applications/MATLAB_R2023b.app/toolbox/matlab/graph2d/box.m % Shadowed
I assume the third one should be the one that is not shadowed?
The 3rd one should not be shadowed.
Remove/rename the other two files.
That has fixed it. Thank you so much!
As always, my pleasure!
