- find your RDR2 data folder

$HOME/.var/app/com.valvesoftware.Steam/.local/share/Steam/steamapps/common/Red\ Dead\ Redemption\ 2/x64/data
- Windows
C:\Program Files (x86)\Steam\steamapps\common\Red Dead Redemption 2\x64\data
- put the startup.meta file in there (do not forget to change the password on the last line)
- play without cheating idiots which crash your game
Honestly, I dont know where your game path is, since I bought the game via steam. Pretty sure you can put the same file, the target directory will just differ. If you got the information, any PR will be highly appreciated.
