.exe crashes on launch

[tHeFinAlGoaT]

Problem Description

When compiling the executable, it behaves unexpectedly:

• When compiled in release mode, the executable crashes immediately upon execution.
• When compiled in debug mode, the executable exits without printing anything.

Environment

• Operating System: Kali Linux (Virtual Machine)
• OS Version: 2024.2 release
• Compilation Method: Using provided make file

Steps to Reproduce

1. Generated a windows/messagebox payload using msfvenom with the provided command.
2. Changed encryption key in both files (fud-uuid-shc.cpp and xor_encryptor.py) to match.
3. Converted the binary payload into a UUID string.
4. XOR encrypted the UUID string.
5. Replaced the default payload in the C++ source file with the encrypted payload.
6. Compiled

Additional Information

• The issue persists across multiple attempts with different payloads.
• No meaningful error messages or logs are generated.
• Tested the compiled executable on both Kali Linux VM (using wine) and Windows 11 version 23H2 without any AVs running.
