Cannot package attached files if QGIS and export directory are the same

[SGroe]

What is the bug or the crash? What were your expectations and what actually happened?

The following Python error occurs when the project is packaged to the directory where the QGIS project is stored.

Usually, I select another directory as destination. I recommend to either force to copy to another directory, or maybe just ignore the exception.

Steps to reproduce the issue

1. Package project (with attached files) to directory where the QGIS project is stored

QGIS version

3.40.9

QFieldSync Version

Operating system version

Reinstall QFieldSync

• [ ] I have a fresh install of the latest QFieldSync version on a new QGIS profile, but the problem persists.
