I'm having errors closing documents with the Matlab Report Generator.

I saw that there was another user with a similar error, but the answer to that question was not applicable to the problem I'm having.
I want to output a large number of plots as figures in a multi-page PDF. Tools from the file exchange did not work, as they require Ghostscript to be installed and I am planning to distribute the final product. Some users suggested using the report generator, which I am doing with a programmatic approach. Prior to the following code, figures with subplots are generated and then saved as .png files in a temporary folder.
import mlreportgen.dom.*
d = Document(PDFFullName,'pdf');
d.StreamOutput = true;
open(d);
P = d.CurrentPageLayout;
P.PageMargins.Header = '0in';
P.PageMargins.Footer = '0in';
P.PageMargins.Top = '0in';
P.PageMargins.Bottom = '0in';
P.PageMargins.Left = '0in';
P.PageMargins.Right = '0in';
Figs = dir('Temp\*.png');
Figs = {Figs(:).name};
for i = 1:length(Figs)
Fig = ['Temp\Fig_' num2str(i) '.png'];
TempPlot = Image(Fig);
TempPlot.Style = {ScaleToFit};
append(d,TempPlot);
end
close(d)
Occasionally, this works perfectly. Most of the time, I get the following error:
Error using mlreportgen.dom.Document/close
Error closing document package: Could not commit changes: Could not rename the temporary package to final
location: Permission denied Permission denied
The PDF file is generated, but it has a size of 0 kb and cannot be opened. Often when this happens I end up with a folder in the same directory that has a name consisting of apparently random letters and numbers. I've tried messing around with a bunch of different parameters and have not been able to determine anything that makes it consistently work or consistently not work.

Hi Robert,
Regarding the document close error, there should be a ‘*_FO’ directory created in the working directory when a report was created. If the creation of that report failed for some reason, that directory is remained and prevents additional reports using the same name. Deleting that directory might resolve this issue.

Hi Robert,
I'm having the same issue and it appears to be linked to this problem on Stack:
Unfortunately in my organisation we don't have the privilege to be able to modify the virus scan parameters as it mentions so I'm still looking for another way around.

I have solved this problem. My issue was that I used a logo in .png form at the top of the report. I tried to include that in the compiled assembly as a file required for the library to run. The report generator therefore cannot find the path to the .png file to close the pdf. i removed the logo and it works fine. Maybe your issue was like this.

If you have a speciail character in the file/folder path, this error may occur. I had experienced this error when I used "[" in the file path. After removing "[", the issue was solved.
