Hello Michael Lang,
Greetings! Welcome to Microsoft Q&A Platform.
I understand that you're trying to add a IP address to a storage account firewall configuration. While doing this, you're getting an error that "STATUS_ACCESS_VIOLATION". The “STATUS_ACCESS_VIOLATION” error in the Azure portal can sometimes be related to browser-specific issues, particularly with Chromium-based browsers like Edge and Chrome.
Try clearing your browser’s cache can resolve unexpected issues and also please ensure that the service principal or user has the necessary permissions on the virtual network in the subscription level. Specifically, they need the ‘Microsoft.Network/virtualNetworks/subnets/join/action permission’. This is typically included in the Network Contributor role also make sure that the user account which accesses the storage account coming from the subnet has an eligible role assignment to access the storage account. So for example, if the user should be able to read and write blob data, add a Storage Blob Data Contributor role for your user.
Browser extensions can sometimes interfere with the Azure portal. Try disabling them temporarily to see if that helps. Some users have reported that disabling certain accessibility settings in Edge can help. You can try going to edge://accessibility and unchecking "Web Accessibility".

If you’ve recently granted permissions or made changes, try refreshing your credentials by signing out and signing back in to the Azure portal. Sometimes, cached credentials can cause issues.
