I've just had Saints Row 4 updated last night on my PC
& also on my today on my laptop with the latest patch,
and so far whenever I go to start up the game, it crashes
as the menu music plays & menu are about to appear.
I then get an error message saying "app already running",
I tried a couple of the solution such as deleting appcache
after shutting down Steam & then restarting the PC and Steam.
Then I tried disabling my anti-virus, still the same result.
I even had to uninstall & reinstall the game entirely.
No matter what I do, it crashes when I load the game up.
