Once a private endpoint rule is deactivated, it isn't immediately removed. Instead, it will be scheduled for purging after a set time period. In your case, the rule is slated for purging at the timestamp mentioned.
This situation can occur in scenarios where a user manually deletes a private endpoint rule while it's still being managed by Terraform, leading to inconsistencies between the Terraform state and the actual resources in Azure. As a result, when Terraform tries to recreate or manage the rule, it runs into conflicts due to the existing deactivated state of the rule.
If the rule is already deactivated, the easiest approach would be to wait for the automatic purging to occur as scheduled.
Otherwise, you can remove the endpoint like this -
