This page will help fix the above dev errors when injecting.

Disable ALL overlays (Discord, Geforce, Medal, Radeon, etc)

Disable Secure Boot

Ensure your game is either in Fullscreen Windowed or Windowed

Uninstall all [Visual C++ Redistributables](https://jaysmodz-guide.gitbook.io/jaysmodz-guide/individual-guides/visual-c++-redistributables) and reinstall them

Stay tabbed into the game throughout injection (focused)

Inject at the character walking screen, not the main menu (you may try injecting at the main menu if the character walking screen does not work)
