I can install it fine and shaders appear to be working, but it crashes with a DirectX error whenever I am in an actual game as soon as I reload shaders (by manually reloading using the UI or alt-tabbing/exiting fullscreen, etc). It then errors as soon as I launch the game again, and I have to disable all shaders to be able to launch the game. Also the UI flickers during gameplay and does not block game input, making it unusable.
There are people in this Reddit thread

saying it works fine for them, but I wonder if it still working, maybe the game has been updated since yesterday which prevents ReShade from working now.
