I'm someone who isn't very tech-savvy or familiar with technical issues.
Occasionally, when I try to edit and update the metadata of a PDF file, I encounter problems where the metadata can't be embedded into the file. For example, I received this error:


calibre, version 8.4.0
Failed for some files: Failed to embed metadata into some book files. Click "Show details" for details.

The PDF format of *Thiền quán con đường của Tuệ giác*:

Traceback (most recent call last):
File "calibre\utils\podofo\__init__.py", line 36, in set_metadata
...
podofo.Error: PdfErrorCode::InvalidXRef
Callstack:
#0 Error Source: private\PdfDeclarationsPrivate.cpp(1404), Information: Stack overflow
From what I understand, this issue is caused by the file itself.
However, is there any way to repair or fix this problem? I'm not comfortable modifying files in technical or advanced ways.

Thank you very much for your time and help.
