Quick answer
On Windows, verify files, update the GPU driver, disable overlays and retry a windowed launch. On macOS, the game has no native support; community reports describe CrossOver or Whisky input fixes, not an official solution.
Windows checklist
- Restart Steam and the PC to clear a stuck launch process.
- Verify the game files from Steam Properties.
- Update the graphics driver from the GPU vendor.
- Disable capture, performance and chat overlays for one test.
- Try a windowed launch and one display at a standard refresh rate.
- If the screen stays black, preserve logs and ask in the game’s current Steam discussions.

macOS is an unsupported route
The Steam page lists Windows, not macOS. Community posts report mixed results through CrossOver and Whisky: one CrossOver user reported good performance after a Unity mouse fix, while another Whisky attempt had broken mouse or scrambled controller input.
