Hi,
Certain Azure services create a resource group containing managed infrastructure resources. You can't delete these resources directly, rather, you must delete the resource that requires them and they will be automatically deleted.
By default, when you create Azure Container Apps Workload profiles environment deployed into your own virtual network, a resource group starting with ME_ is created to contain infrastructure resources (Azure Load Balancer is one of the resources).
If Container Apps is the reason the resources exist and you no longer need it, you may consider deleting so that the related managed resource group (and its resources) will be removed. Please make certain you are no longer using before deleting.
