FB21458882 - SFSafariSettings openExtensionsSettingsForIdentifiers randomly fails with SFErrorDomain error 6

[lapcat]

iOS 26.2 introduced the new method SFSafariSettings openExtensionsSettingsForIdentifiers:
https://developer.apple.com/documentation/safariservices/sfsafarisettings/openextensionssettings(foridentifiers:completionhandler:)?language=objc

In my testing, this method seems to fail randomly. Attached is a sample Xcode project demonstrating the bug.

Steps to reproduce:

1. Open and build the attached Safari extension app project
2. Run the app on iOS 26.2
3. Press the Open Safari Extensions Settings button in the main window of the app
4. Force quit the SettingsBug app and the Settings app and repeat steps 2 and 3 until there is an alert in the SettingsBug app

Expected results: Safari Extensions Settings opens

Actual results: SFErrorDomain error 6
