2. Build for iOS
3. Open the Xcode project and deploy to iPhone 8 Plus
4. On the app press button "Single"
5. Make sure that the track is "CANADA"
6. Press "Play single race"
7. Observe the black screen

Expected result: the race is loaded and able to race
Actual result: when loading the race getting a black screen

Reproduced on:
2017.4.3f1 2017.4.10f1

Getting script errors in 2018.2.6f1 2018.3.0a11

Notes:
When building with Unity 2017.4.10f1 and opening the app through Xcode (Version 9.4.1 (9F2000)) everything works as expected, no black screen.
When the app is closed and cleared from the app drawer, opening the app and doing the same steps produces the same black screen on the loading screen.
