Crash on startup in MarkObjectAsRoot()

I updated from 2017.3 to 2018.2, and now Android builds crash upon startup (black screen after splash screen) with the following call stack:

0 libunity.so 0x00000000a1bda0fc MarkObjectAsRoot(Object const&, GarbageCollectorThreadState&)
1 libunity.so 0x00000000a1583fb8 GameObject::MarkGameObjectAndComponentDependencies(GarbageCollectorThreadState&) const
2 libunity.so 0x00000000a1bd9498 GarbageCollectSharedAssets(bool, bool)

5 libunity.so 0x00000000a1dca658 PreloadManager::WaitForAllAsyncOperationsToComplete()
6 libunity.so 0x00000000a14639d0 UnityPlayerLoop()
7 libunity.so 0x00000000a14671a4 nativeRender(_JNIEnv*, _jobject*)
8 mnt@asec@com.IronZog.WarOfConquest-11@base.apk@classes.dex0x00000000a307866b <unknown>

This same crash occurs whether I build using mono or il2cpp. Any ideas on how to solve this?

 

Same problem.
No errors (also checked with the monitor.bat of the Android Studio tools).

 

I found that I'm getting the very same crash in Windows builds. Works fine in the Editor though.

Since the problem is not restricted to Android builds I've posted about it in the general support forum here:

WILEz1975, have you noticed whether Windows builds crash in this same way for you?

 

For anyone still having this crash -- I posted about how I was able to solve it, on this thread:
