Error occurs when exporting Products via Tools → Export in WordPress 6.9

[NitsPatel]

In WordPress 6.9, exporting Products using the built-in Tools → Export functionality results in an error when attempting to download the export file.

Steps to Reproduce

• Install and activate WordPress 6.9
• Ensure WooCommerce is installed and activated
• Go to Dashboard → Tools → Export Select Products using the radio button Click Download Export File

Expected Result

The Products export should download successfully as an XML file containing all product data.

Actual Result

An error occurs during the export process, and the Products XML file is not downloaded.

Environment
WordPress Version: 6.9
PHP Version: 8.2.27
Theme: Twenty Twenty-Five
Plugins: WooCommerce (only)
Browser: Chrome

Additional Notes

• The issue persists even when using a default theme.
• The issue occurs consistently when exporting Products.
• Other export options (e.g., Posts, Pages) work as expected.
