[iOS][IL2CPP] Crash on il2cpp::metadata::Il2CppTypeHash::Hash when the SR Debugger is opened and then closed
How to reproduce:
1. Open the attached project
2. Go to File-> Build Settings-> Switch to iOS Platform
3. Build for iOS and deploy the Xcode project to the iOS device
4. Press the Continue button if it is shown
5. Press at least 3 times in the top left corner to open the debugger (I just kept pressing fast until it opened)
6. Close the debugger
7. Press the Play button
----Crash----
Reproducible with: 2018.3.14f1, 2019.1.0f2, 2019.2.0a3
Devices:
iPhone 7 (iOS 12.1.4)
iPhone 6 (iOS 11.3.1)
Note: Could not test in earlier versions and Android because errors are thrown and also, could not test versions above 2019.2.0a3
(You can find SR Debugger in the asset store)
