AccessViolationException Occurs While Running DiffGenTool on win-x64

[Youngwoong-Han-Qcells]

Hello,

I am encountering an issue while running DiffGenTool from the Preview folder in the iot-hub-device-update-delta repository on a Windows 10 win-x64 environment. The tool crashes with a System.AccessViolationException error.

Steps to Reproduce
I executed the following command:

PS C:\Users\youngwoong.han\Downloads\Diffgen\win-x64> .\DiffGenTool.exe "C:\Users\youngwoong.han\Downloads\Diffgen\win-x64\adu-update-image-raspberrypi3-1.2.0.swu" "C:\Users\youngwoong.han\Downloads\Diffgen\win-x64\adu-update-image-raspberrypi3-20241211045834.swu" "C:\Users\youngwoong.han\Downloads\Diffgen\win-x64\delta-image.swu" "C:\Users\youngwoong.han\Downloads\Diffgen\win-x64\logs" "C:\Users\youngwoong.han\Downloads\Diffgen\win-x64\output"

Observed Behavior
The tool begins tokenizing the SWU files and then crashes with the following fatal error:
Fatal error. System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Partial Log Output:
[Info] ThreadId1 Loading tokens from ... [Info] ThreadId7 Testing if archive is format: CpioArchives.NewAsciiCpioArchive [Info] ThreadId1 Archive is of format: CpioArchives.NewAsciiCpioArchive ...

Environment
Operating System: Windows 10, version 10.0.22631
Architecture: win-x64
Tool Version: DiffGenTool (Preview folder)
SWU Files:
adu-update-image-raspberrypi3-1.2.0.swu
adu-update-image-raspberrypi3-20241211045834.swu

What I Have Tried
Ensured both SWU files are present and valid.
Ran the command with administrator privileges.
Verified that I am using a 64-bit environment.
Confirmed that no file path contains special characters.
