Hello @amzmmarc, welcome to the QuickSight Community!
This looks like the same issue experienced in this community topic from a few months ago. It seems IAM configurations need to be made. I’d recommend checking out this documentation that another QuickSight expert recommended to solve this problem.
I will mark this as a solution for now, but if you continue to experience issues after integrating your QuickSight account with IAM Identity Center, then please let me know!
