S3 Download error Conflicting file exists

**S3 Download error on hosted azure DevOps with windows agent**

I have nested directories in s3 bucket, the task creates the top level directory as a 0 byte file, when the task continue to download a file under that directory it fails with: Unable to create directory '`D:\CD\1\templates\dev\-1\Email`'. Conflicting file exists: '`D:\CD\1\templates\dev`'.
Overwrite flag is set to true.

**To reproduce**

Steps to reproduce the behavior:
1. Create s3 bucket with files in nested directories like `dev\-1\Email\en-us.txt`
2. Create a pipeline with latest S3 Download task v1.13.0 with windows agent version 2.153.1 to download all the bucket to the agent default working directory.

**Expected behavior**

A Successful step with the bucket contents on the destination directory.

**Your Environment**

- On-prem
- Azure DevOps version: Dev17.M153.3
- AWS Toolkit for Azure DevOps version: 1.13.0

Start with the S3 Download task at version 1.13.0 and reproduce the failure on a Windows agent using nested bucket paths such as dev\\-1\\Email\\en-us.txt. Verify the task does not create a conflicting zero-byte file and that the pipeline completes with all bucket contents in the destination directory.
