For anyone else that runs into this or a similar issue, the support request is still going but I have found a work around.
I was packaging with Thinapp version 5.1.0-2079447 (The guides call for 4.7.2 or higher)
I re-packaged with Thinapp version 4.7.3 and it appears to functioning correctly. This isn't really a proper solution in my eyes, but it is working.
