如果您无法解密AWS GovCloud中的S3存储桶中的对象，即使您具有管理员访问权限，请检查您的键和证书是否正确安装。以下是使用AWS SDK for Python解决此问题的示例代码：

import boto3
from botocore.exceptions import ClientError

# Setup client with appropriate region and credentials
s3 = boto3.client('s3', region_name='',
                  aws_access_key_id='',
                  aws_secret_access_key='')

# Bucket name and object key
bucket_name = ''
object_key = ''

try:
    # Use client to get object from S3
    response = s3.get_object(Bucket=bucket_name, Key=object_key)

    # Read object data
    object_data = response['Body'].read()

    # Successfully decrypted object, do something with object data

except ClientError as e:
    # Catch the exception if unable to decrypt object
    if e.response['Error']['Code'] == 'AccessDeniedException':
        print(f"Unable to decrypt object '{object_key}' from S3 bucket '{bucket_name}'")
    else:
        raise
