NullReferenceException when running recipe or selecting the event recipe up on installing orchard core.

I'm using orchard core version 1.0.0-beta-3-70650 with AspNetCore 2.2.0

Here is the error I get

An unhandled exception occurred while processing the request.
NullReferenceException: Object reference not set to an instance of an object.
OrchardCore.ContentManagement.Display.ContentItemDisplayManager.BuildDisplayAsync(ContentItem contentItem, IUpdateModel updater, string displayType, string groupId) in ContentDisplayManager.cs, line 68

Gave this a go myself running 1.0.0-beta3-70668 and it works fine. When we next get a chance we'll debug this on your machine. If I remember rightly it was the FlowPart override that was causing the issue. Looking at the original FlowPart there haven't been any changes for quite some time.
