Publishing build artifacts fails with error EEXIST: file already exists

Question

we are using the VSTS task "Publish Artifact". Recently it started to randomly give an error:

Publishing build artifacts failed with an error: Unable to create directory. EEXIST: file already exists.

This happens when the task is about to create the directory where to publish.

Here are some of the logs

To troubleshooting the issue, you can check with below aspects:

Check if the share path is accessible

You can manually access to \\appbld\C$\WDX\PublishArtifacts\Build Trunk to check if you can access.
Check if the write permission is allow

Check the Write permission for the share path is allowed or not.
Check if the private agent run as the account when login the agent machine (if the agent run as service)

Services App -> select the vsts agent service for the private agent -> properties -> Log On Tab -> check if the account same as you login the agent machine.
