Hello,
It is my understanding that plot function is not working in your case, and you are receiving the mentioned error.
To fix the error you can insert the plotting code inside if block as:
clc
clear all
figure;
t=0:0.1:2;
g = groot;
fig = get(groot, 'CurrentFigure');
if ~isempty(fig) % true if there are no open graphics objects, false otherwise
% code to plot
plot(t,sin(t));
end
You can also refer the following link for more details -

I hope it helps.
