This is because the game files are encrypted with Windows EFS (Encrypted File System).
There is a private SSL Certificate attached to the file only unlockable through the Windows Application Store using your User SID.
Although, you can inject the UWPDumper.dll and decrypt the game from memory:

I managed to extract the flat file list of the PAK but am unable to do anything with the .uasset files since I cannot find the AES Encryption Key in the client's EXE

That's the Windows EFS encryption, use the UWPDumper previously posted to get clean copies of the files.

I haven't had any luck looking at the file list in the pak or anything. How should I go about doing that? Kind of new at this. I used UWPDumper to get the .pak file. I also made a dump file and pulled strings out of it, but it's a mess and searching through it didn't turn up much. Can anyone point me in the right direction for finding the password to this .pak? Or even finding the file list as marn did. Thanks.

I want continue, where he stopped. Sadly UWP Injctor now crashes when you try to dump, seems they added a Protection? Any other way to dump?
