The PC port of Batman Arkham City was horribly implemented and littered with issues involving, DirectX11, Nvidia PhysX, and .NET.
If the pre-game launcher/menu launches (the launcher that displays, Play, Settings, View ReadMe File, Exit)
go into Settings and disable anything related to DirectX11 and Nvidia PhysX.
If the following doesn’t work you may need to install an older DirectX version (DirectX 9 I believe) and/or edit a PhysX DLL file. Batman Arkham Asylum has very similar issues as well, I believe solely installing an older DirectX version fixes it though.
Take all this with a grain of salt because it’s been a very long time since I’ve played Batman Arkham City.

I’d like to add that if you try to install the game on W11, it gives the same issues. It’s hilariously broken.
I have seen that Proton Fixes (getting the random DLLs) is helpful in such scenarios.
Strange. I’d try checking the files in Steam.
