This is the Xbox GamePass PC version. No corrupt save or mods, reinstalled thrice over to different 3 different drives. Windows is newly reinstalled from just after Christmas–I literally just redownloaded my entire 15 TB+ Steam, Origin, GOG, Epic games. No AV. Nothing extra at startup. Everything is disabled in the Startup tab of task manager except for Xbox App Services, Logitech, NVIDIA, Realtek drivers and Windows Security notification icon.
I will just put this on Paradox since all of the other Paradox games (Xbox GamePass PC and Steam) are slow to load as well. This is a PC built only in June.
