Private session in RDR 2 Online (PC only)

How to create your own private session in Red Dead Redemption 2 Online (PC only method):
* (this is exactly the same method as in RDO Lobby Manager, but manually, without using any app)

1. Open notepad and copy to it the text from here: https://pastebin.com/tckzCWEi.
2. Write anything instead of "your_code_word" at the very end of the text you've just copied.
3. Save it with any name, then rename it with "startup.meta" (without quotation marks, [.meta] need to be file extension instead of [.txt]).
4. Find [\x64\data] subfolder inside the game directory. If you have your game on Steam, it's here:
C:\Program Files (x86)\Steam\steamapps\common\Red Dead Redemption 2\x64\data. There is supposed to be only one folder "errorcodes".
5. Copy the startup.meta file you've just created into the [\data] folder.
6. Now when you load the game, you are the sole player in your session. Note that you can't participate in free roam events, take part in story missions or anything of the sort that requires other players from the lobby.
7. You can invite your friends to your private session, they just need to do the same on their computers (steps 1-5) and write exactly the same string as a code word at the end of "startup.meta" text (as in step 2). If there are more than one player in your private session, you can join free roam events, just leave the posse so you can be competitors.
8. Whenever you want to pause playing alone and come back to regular session with other random players, before loading the game open the [\Red Dead Redemption 2\x64\data] folder and remove "startup.meta" file from there, or just disable the file by renaming it (for example, put an underscore, like "_startup.meta").

Enjoy. There are no more annoying griefers and hackers, animals and random quests/encounters spawn frequently all around you. :)
