Export to pdf broken on kde linux

Kubuntu 25.04, Obsidian AppImage 1.8.10 - Export to PDF stopped working yesterday (09/05).
The following appears in the journal when I use the ‘save’ button on the OS modal to save the PDF export:

[email protected] Only URIs with the "file://" scheme are allowed

I am still trying to learn what this message means exactly and identify what system packages were updated before I discovered the issue.

In the meantime would those who experience the export issue on KDE mind to open the KSystemLog app (or otherwise just check the logs) and check if they get the same log entry during export?

Thank you
