Is this trainer also for Hearts and stone Expansion?
I played it on the GOG version and it worked just fine so I'd assume it also works for the Steam version as well.
If it's still working for the game, you'll be Ok in Hearts of Stone.

On the dlc for witcher 3 heart of stone the game will suddenly crash but the trainer works fine during single player main missions. (Steam version)

It was fine when I played it. Has there been any other recent updates or patches since the last DLC?
You ran trainer and game As Admin? Disabled all Anti-Virus or add exceptions? Are you running any Mods?
