getting error d6 when starting game from launcher

I keep getting the error code D6 after I press the launch button from the launcher, I already have uninstalled and reinstalled the game twice today and have no clue what could be causing it.

I might have flipped the error code around by mistake the error code shows every time I launch the game now, never had the issue before
