SpaceShooter DynamicInvoke error while playing

Reproduce the failure by opening the SpaceShooter sample in Unity 2021.2.5f1 and playing the bootstrap scene. Start with the stack trace locations in AssetDatabaseProvider.cs and DelayedActionManager.cs from Addressables 1.19.11, then compare the failing asset-load path with the sample setup. Done means the bootstrap scene plays without the repeated DynamicInvoke or NullReferenceException.

Hi, I am new to Addressables and wanted to try the samples in this repo,
When I tried to open SpaceShooter with unity version 2021.2.5f1 and played the bootstrap scene, after few frames I got the following exception in console:

Exception thrown in DynamicInvoke: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object

any suggestions to why it would happen? when I click unpause it resume and then thrown again :(

Thanks!
