AWS：S3 存储桶 AWS 您无法授予公共访问权限，因为此帐户已启用阻止公共访问设置

我想向所有人公开 S3 存储桶，但是当我这样做时，我的访问被拒绝，它说

You can't grant public access because Block public access settings 
are turned on for this account. To determine which settings are 
turned on, check your Block public access settings.

当我进入公共访问设置时，一切都关闭了。

我确实设置了 IAM 用户并且用户具有 AmazonS3FullAccess 策略

{
"Version": "2012-10-17",
"Statement": [
    {
        "Effect": "Allow",
        "Action": "s3:*",
        "Resource": "*"
    }
  ]
 }

我确实在存储桶上设置了策略

{
"Version": "2012-10-17",
"Id": "Policy1557294263403",
"Statement": [
    {
        "Sid": "Stmt1557294241958",
        "Effect": "Allow",
        "Principal": {
            "AWS": "arn:aws:iam::726051891502:user/borroup-admin"
        },
        "Action": "s3:*",
        "Resource": [
            "arn:aws:s3:::borroup",
            "arn:aws:s3:::borroup/*"
        ]
      }
    ]
 }

我确实在存储桶上设置了 CORS 配置编辑器
