Aspose.Words version 23.2.0 on Windows
Aspose.Words hangs on MailMerge.Execute (+ high memory and cpu usage)
Minimal repro code:
string fileName = "sample.docx";
Document doc = new(fileName);
doc.MailMerge.UseNonMergeFields = true;
doc.MailMerge.Execute(new string[] { "field" }, new object[] { "value" });
doc.Save("sample_out.docx");
sample.docx (27.4 KB)
