Hi ,

I have just had the same issue. I’ve modified the UAT to pass -encrypt through to UnrealPak, defined my AES key, succesfully encrypted the package - unpaking it after removing the AES key and rebuilding UnrealPak yields encrypted files - but when I actually try to run the staged build containing the encrypted .pak, it crashes immediately without logging anything useful.

So I ran the staged executable in Visual Studio and it crashed at AES.cpp:1114 with a write violation exception.

On the other hand, extracting the encrypted .pak with UnrealPak works well, which means there is a problem with load-time decryption.
