Error 0x8007005 when attempting to execute a dtsx package from the command line

I am getting this error when attempting to execute a DTSX package from the Windows command line when logged in as a service account inside a domain.

Code: 0xC0011002
Source: {6DB934F3-5312-4C7C-9E59-D8CF30910966}
Description: Failed to open package
\\some_server\some_export_folder\some_export_ssis_package.dtsx 
Access denied due to error 0x80070005. 
This occurs when loading a package and the 
file cannot be opened or loaded correctly into the XML document.

The service account has total control over \\some_server\some_export_folder.

This same package exports correctly when I execute it with my own login.

I have read that it might be this GPO Take ownership of files or other objects and I've read this Why does a package that runs well on dtexec fails to run under SQL Server Agent job but I am not running this package as a job. Also, this DTSX needs to run under the context of a Windows Active Directory service account and not as an administrator.

Aside from Total Control over the folder, what other permissions are required in Active Directory or on the directory itself?
