Why does this example from MathWorks work on Windows but not on Mac?

I'm trying to run this example straight from the MathWorks LeanerFMWaveform page.

fs = 500e3;
sLFM = phased.LinearFMWaveform('SampleRate',fs,...
    'SweepBandwidth',200e3,...
    'PulseWidth',1e-3,'PRF',1e3);
lfmwav = step(sLFM);
nsamp = size(lfmwav,1);
t = [0:(nsamp-1)]/fs;
plot(t*1000,real(lfmwav))

When I run it on MATLAB on Windows, it works as expected and plots the signal. When I run it on MATLAB on Mac, I get this error:

Error using plot
Too many input arguments.

I'm running version R2021a on both operating systems. Why is this not working on Mac?

which -all plot

It's not win v. mac but that you've shadowed plot on the failing machine.
