Export to PDF fails on Kubuntu

[missingfaktor]

What I’m trying to do

I am trying to use the Export-to-PDF feature in Obsidian, but it fails. A file selector window briefly shows up and vanishes immediately, leaving no exported file. The KDE notification bar shows the error message in the attached screenshot: xdg-desktop-portal-kde Closed Unexpectedly.

Things I have tried

I have checked the Obsidian help documentation and forums but could not find a resolution for this issue. I have tried the following steps to debug the issue:

1. Restarting the application: Restarted both Obsidian and the xdg-desktop-portal-kde process, but the problem persists.
2. Testing in Safe Mode: Enabled Obsidian Safe Mode to rule out plugin interference, but the issue still occurred.
3. System Checks: Verified that xdg-desktop-portal and related components are installed correctly on my system.
4. File Permissions: Ensured the directory has write permissions.

Unfortunately, none of these steps resolved the issue. It seems like an interaction between Obsidian’s Export-to-PDF feature and xdg-desktop-portal-kde is causing the crash.
