Octave 11.1 and 11.3 test on windows 11 with all toolkits (qt, gnuplot, ftlk)

Saving as svg like
print( [pathname,filename,".svg"], "-dsvg");
freezes and
print( [pathname,filename,"_2.pdf"], "-dpdf" );
crashes octave or freeze it.
Using instead
print( [pathname,filename,"_2.pdf"], "-dpdf","-S800,600" );
always only freezes octave forever.

Any 2D plot does this for me, se below

clear all;
close all;

% wafer circle
t = linspace(0.25-pi/2,2*pi-0.25-pi/2,100);
circsx = 25.2.*cos(t);
circsy = 25.2.*sin(t);
circsx(end+1)=circsx(1);
circsy(end+1)=circsy(1);

plot(circsx,circsy,"k");
hold on;

% show it
hcb=colorbar;
colormap(flipud(rainbow));
hold on;
grid off;
axis("off");
shading flat;
axis([-25.21 25.21 -25.21 25.21]);


% save png
%print( [pathname,filename,".png"], "-dpng","-S640,500" );
print( "test.pdf", "-dpdf" );
