I think based on the error message that you have missing or unavailable resource key in your Microsoft Family account, particularly when organizing files in Azure Files.
Start by verifying that the resource key 'search box conif key'
exists and is accessible within your account.
Occasionally, service disruptions can lead to resource unavailability so you need to visit the Azure Service Status page to see if there are any ongoing issues affecting Azure Files.
If you've recently made changes to your account settings, permissions, or configurations, these modifications might have impacted resource availability.
If the issue persists after performing the above steps, it's advisable to reach out to Microsoft Support for personalized assistance.
