When trying to access the Defender for Cloud Inventory page most of the time the page doesn't load with the below error shown. However, rarely the page will load correctly. This is occurring on my Azure account as well as multiple other accounts. The error occurs regardless of the subscription or virtual machine being checked. Is there anything that can be done to correct this?

An error has occured while invoking RPC method 'handleRemoteCallback' from extension 'Microsoft_Azure_Security_R3'. Session ID: XXXXXXXXXXXXXXXXXXXX Error details: {"extensionName":"Microsoft_Azure_Security_R3","callbackName":"handleRemoteCallback","parameters":{"callbackIdentifier":"getResourceHealthExtensions","objectIdentifier":"Microsoft_Azure_Security_R3_remoteObject_40","callbackData":[{"resourceId":"/XXXXXXXXXXXXXXXX","resourceType":1}]},"error":{"stack":"###RPC_Exception### Error: ECS feature flags for project 'Defenders' are not initialized.
