I have the dumped .exe from a game, and it gives me only the main static key

[Arthurfogo7]

It works for most files, but not all of them, but if I can't get the AES key through the .exe, what should I do? I need to unpack that .pak file.

Here is the dumped .exe and the .pak that can't be extracted with the main static key. Please, I need help.
