Unity Engine

I switched to IL2CPP for android store, build went fine, Google published it, but when i try to open it, it just says app stopped running before even going to the splash screen. When i go into unity to “build and run” on my galaxy 9+, i get this console error;

InvalidOperationException: EnsureRunningOnMainThread can only be called from the main thread
UnityEngine.Object.EnsureRunningOnMainThread () (at :0)
UnityEngine.Object.GetInstanceID () (at :0)
UnityEngine.Object.IsNativeObjectAlive (UnityEngine.Object o) (at :0)

UnityEngine.Object.op_Inequality (UnityEngine.Object x, UnityEngine.Object y) (at :0)
UnityEngine.Events.PersistentCall.ValidateTargetAssemblyType () (at :0)
UnityEngine.Events.PersistentCall.OnAfterDeserialize () (at :0)

ive tried the following:

1.) Created a new keystore, and signed
2.)
3.) disabled strip engine code.
4.) last resort, updated to 2020.1.0a16
5.) Tried download from store on several different android devices, same issue.

Still won’t build to my device, and i seem to have a game in the store that wont open when installed…any ideas? I’m at a loss here.

The first thing I’d to is revert my project back to the state where you successfully created your last successful build and see if you have the same issue, using the same Unity version you were previously using. I’d also try just building instead of “build and run”.

i did try that, and build works, which is what i submitted to the play store, but now when I, and my beta testers download from the store, the app crashing instantly before the unity splash screen.
