Linked Block DimStyles causing crash in Rhino 7

I’m running into some unexpected behavior when working with blocks that have annotations in them.

If I insert a block, for example a Title Block, with annotation objects, everything seems fine if I use Embedded + Linked, or Linked with the Layer Style set to Active.

However, if I use a Reference Layer Style:

And then go to the Annotation Styles:

I see them in the Drop down on the left, but if I click on one, to see the settings, then Rhino 7 crashes without any warning or prompts.

If it is either of the other two scenarios (Linked w/ Reference Layer Style OR Embedded + Linked) then it seems to work fine, though there is a noticeable pause as it tries to load the Annotation Style window the first time.

The crash does still save a RhinoDotNetCrash file to the desktop:

[ERROR] FATAL UNHANDLED EXCEPTION: System.InvalidOperationException: Dispatcher processing has been suspended, but messages are still being processed.
at System.Windows.Threading.Dispatcher.WndProcHook(IntPtr hwnd, Int32 msg, IntPtr wParam, IntPtr lParam, Boolean& handled)

at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)

Can certainly use the other block settings for now, but seemed important to note.

I think it would be helpful if you posted the results of running Rhino’s SystemInfo command and a .3dm file that demonstrates this.

Thanks for the reminder!

Here’s a model that simply has 1 leader in it, with a dim style copied from one of the Built-In styles.
