troubles with ginput function

I have troubles with ginput under Windows 11. A lot of MATLAB code which works well under Windows 10 does not function correctly under Windows 11. What can I do? I suppose this is not a MATLAB problem.

for example the following code

close all

axis([0,1,0,1])

[x,y]=ginput();

m=length(x)-1;

tn=0:m;

t=linspace(0,m,500);

xg=spline(tn,x,t);

yg=spline(tn,y,t);

plot(x,y,'o',xg,yg)
