This does not apply to all games. Games like Baulder's Gate 1 and 2, Borderlands 1 and 2, Undertale, Bioshock 1 don't work. However games like Total War: Rome 2, Dark Souls 3, Skyrim, Bioshock 2 etc works absolutely fine. The problem isn't that the game doesn't work, it's that it works fine after I install it, but doesn't after some time, maybe after a restart. What can I do to fix this?
