BeamNG.drive 0.4.0.6 fails to launch (listed as 32-bit / D3D9): "Starting your game..." stalls, then returns to the library

Environment

• Madeira: 0.1.3, build 4
• Device: iPhone (add your model), iOS (add your version)
• Install: normal SideStore sideload with extensions kept; Settings shows JIT and Memory+ green, Ready to play
• Source: Steam, launched from the library's Play button

Game

• BeamNG.drive 0.4.0.6
• Madeira's Game details page lists it as 32-bit, D3D9, 3.3 GB

Steps to reproduce

1. Open Madeira, go to the library, open BeamNG.drive, tap Play.
2. Steam signs in and confirms the license.
3. The "Starting your game..." screen appears with its timer.
4. At about 17s the timer stops and Madeira drops back to the library.

Expected: the game window opens.

Actual: no window, no error message, no crash dialog, the launch simply gives up and returns to the library.
