Indicators crash when IsOverlay = true

Hi

This is related to a post I made a couple of weeks back but didn't get any help with it.

When I create an indicator using .NET6, I get the following when I add it to a chart:

Currently, all the indicator does is create a single StackPanel, with a Single Textblock in it. By default it doesn't have a IsOverlay parameter set and so defaults to false. When I set IsOverlay = true so the stackpanel is displayed in the price chart, I get this error. I can't figure out how to debug it as the problem occurs in the Indicator declaration before the Initialize method is even invoked.
