Big Box crashes a lot and gives this error

[OmenBoy]

I'm on Windows 10, Big Box ver. 6.9 beta 9. It usually happens when exiting a game. Also I'm using RocketLauncher with it.

System.NullReferenceException: Object reference not set to an instance of an object. at (<>c__DisplayClass69_0 ) at BigBox.ViewModels.GamesViewModelBase.<>c__DisplayClass69_0.<DelayDispose>b__0() at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart()

Thank you Damien; this should be fixed for the next beta.
