[!] Error : Missing cookie, unsupported pyinstaller version or not a pyinstaller archive

Hello! I've been struggling to unpack the file for 5 days now with no success. I've even tried using Cutter, but nothing works. Can you help, please?

I ran strings.exe LocalBackend.exe | findstr /i "PyInstaller PYZ pyi MEIPASS" and found numerous mentions of PYZ and pyi, which are clear indicators of PyInstaller. Then I extracted the PYZ archive using a script, but couldn't proceed further. I came across your tool, but I'm having trouble getting it to work as well.

Hi, this is a Nuitka compiled binary, not pyinstaller. You can search for the string "NUITKA_ONEFILE_PARENT".
