Error occurred when I tried to copy tiledlayout object to mlreportgen.report.Figure and append it to mlreportgen.report.Report in App Designer

Hello team and community,
I am working on an app in MATLAB App Designer.
Here I tried to generate a report from mlreportgen.report and mlreportgen.dom.
I initially plotted my reults in an TabGroup with tiledlayout as the attachment image.
And I would like to copy this plot into a figure and create it in a mlreportgen.report.Figure with following code.
% The part of the code that went wrong
% Figure results
sec2_2 = Section;
sec2_2.Title = 'Results plot';
for i = 3:numel(app.TabGroup2.Children)
t = app.TabGroup2.Children(i);
pos = get(t,'Position');
f1 = figure('Visible','off');
set(f1,'Position',pos)
s = copyobj(t.Children,f1);
fig4 = Figure(s);
append(sec2_2,fig4);
close(f1);
end
append(ch2,sec2_2);
append(rpt,ch2); % error occured here
However, I received the following error and I have hard time to understand want could be wrong for debugging.
Interestingly, when I used pause for degugging and I excuted the above code in another script, I was able to excute without error.
Could anyone explaine why this error occured?

Hi Jesse,
Here is sample code for copying or exporting a figure from tab-group into a report using ‘mlreportgen’ function:
methods (Access = private)
% Code that executes after component creation
function demoFunction(app)
m = 2;
n = 1;
x = 1:10;
y = 2*x+1;
app.tiledlayout = tiledlayout(app.Panel,m,n);
ax1 = nexttile(app.tiledlayout,1);
plot(ax1,x,y);
ax2 = nexttile(app.tiledlayout,2);
plot(ax2,x,2*y);
end
% Button pushed function: CopyPlotButton
function copyFigure(app, event)
import mlreportgen.report.*
appPanel = app.TabGroup.Children(1).Children(2);
app.tiledlayout = appPanel.Children(1);
t = app.tiledlayout.Children;
fig = figure('Visible','off');
copyobj(t,fig);
pos = fig.Position;
rpt = Report('example','pdf');
add(rpt, "Sample Figure");
figReporter0 = Figure(fig);
add(rpt,figReporter0);
rptview(rpt)
end
end
In the above code, ‘demoFunction’ is a startup function for the app which creates tiled layout and adds sample plots to the two tiles under the first tab in the tab-group.
Moreover, ‘copyFigure’ is a callback function which is called when the ‘copyFigure’ button is clicked on the App. This function exports the entire tiled layout with sample plots into the report created using the ‘mlreportgen’ function of MATLAB.
