Security Score Missing in AWS Security Hub: Investigating Possible Causes

Yesterday, while conducting a routine check of my Security Hub, I encountered an issue where the security score was inexplicably absent from the hub. Delving deeper into the matter, I discovered that all the security standards had been deactivated for unknown reasons. Interestingly, a review of the CloudTrail logs revealed no traces of any changes made to the security settings.

To troubleshoot, I manually toggled the standards on and off to observe if these actions were being logged. The logs were generated when I performed these manual adjustments. It's important to note that our team diligently monitors the security score on a weekly basis, affirming that the standards were indeed enabled prior to this incident.

Has anyone else encountered a similar anomaly or can provide insights into why this might have occurred? Additionally, during this investigation, I noticed the appearance of two new standards. Could it be plausible that a recent update inadvertently caused the disabling of my security standards?
