Additional context

I’m using a MacBook Air (M1) with macOS Sequoia 15.1 and installed QGIS 3.40.0-Bratislava via MacPorts. To troubleshoot this issue, I’ve tried the following steps:
• Checked directory permissions to ensure that QGIS has write access.
• Attempted to set up faulthandler to capture error logs in an external file.
• Created and tested with a new QGIS profile to rule out profile-related issues.
• Granted QGIS “Full Disk Access” in macOS security settings.
• Reinstalled QGIS to ensure a clean installation.

Despite these efforts, the error persists on every startup. Any guidance on resolving this issue would be greatly appreciated. Thank you.
