Problem with Graphics.Plot on Linux system

Dear Prof. Haverkort,

When I was running the Quanty script regarding the DMFT calculation, in specific, 06_Core_Level_Spectroscopy_DMFT.Quanty, with the lines

Pl  = Graphics.Plot(G, GammaL, GammaG, {{"Negate",true},{"plotRe",false},{"Frame",{{"Ymin",0},{"Ymax",30},{"Xmin",-4},{"Xmax",4},{"dYTick",5},{"dXTick",0.5},{"FontSize",0.03},{"YFormat","%3.0f"},{"XFormat","%3.1f"},{"XLabel","E [t]"},{"YLabel","G"}}}})
PlSVG = Graphics.ToSVG(Pl)
file,err = io.open("G.svg",'w')
file:write(PlSVG)
file:close()

I could only see the frame of the figure but there is no data of G plotted.

However, in another script with the command

PlG = Graphics.Plot(G,0,GammaG,{{"PlotPoints",2000},{"Frame",{{"Ymin",-YRange},{"Ymax",YRange},{"dYTick",dYTick},{"Xmin",Emin},{"Xmax",Emax},{"dXTick",2},{"XLabel","Energy [t]"},{"YLabel","Intensity"}}}})
SVGPlG = Graphics.ToSVG(PlG)
file = io.open("Plots/PlG_"..tostring(i)..".svg",'w')
file:write(SVGPlG)
file:close()

I could get the plot without any issue.

I tried also on MacOS, and both worked without any problem.

Do you have any clue about this problem?

Thanks a lot for your time!
