First of all it seems that this is common issue. I read all the topics I could find on the forum here, but there was no clear answer.

Adding drawnow didn't work.

And, Yes, the function is interruptible.

f = waitbar(0,'Loading','Name','Exporting...',...
    'CreateCancelBtn','setappdata(gcbf,''canceling'',0)');
for k = 1:16
    
    if getappdata(f,'canceling') == 1
        break
    end
    
    figure('Visible', 'off');
    
    ExpFig = trisurf(F,P(:,1),P(:,2),P(:,3),app.UITable4.Data(:,k));
    
        
    exportgraphics(gcf, string(file) ,"BackgroundColor","none","ContentType","vector","Append",true);
    
    close;
    
    
    waitbar(k/16, f, sprintf('Export Progress: %d %%', floor (k/16*100)));
    pause(0.1);
    drawnow();
    
end
delete (f);
msgbox('Export Completed!');

You forgot to set the value first and you reversed 0 and 1:

f = waitbar(0,'Loading','Name','Exporting...',...
    'CreateCancelBtn','setappdata(gcbf,''canceling'',1)');
setappdata(f,'canceling',0);
for k = 1:16
    
    if getappdata(f,'canceling')
        break
    end
    
    figure('Visible', 'off');
    
    ExpFig = trisurf(F,P(:,1),P(:,2),P(:,3),app.UITable4.Data(:,k));
    
        
    exportgraphics(gcf, string(file) ,"BackgroundColor","none","ContentType","vector","Append",true);
    
    close;
    
    
    waitbar(k/16, f, sprintf('Export Progress: %d %%', floor (k/16*100)));
    pause(0.1);
    drawnow();
    
end
delete (f);
msgbox('Export Completed!');
