Debugger causes App to freeze after first render #10545

Describe the bug

The Loaded event handlers are called, but the app is not interactive. No hover effects/animations, Clicking does not invoke click handlers.

This is only a problem when starting up with the debugger.

It seems like it is a race condition. Only became a problem after upgrading to a new cpu. More likely to reproduce on a fast load, when everything is "hot" i.e. it happens when in the edit-compile-run cycle.

Steps to reproduce the bug

I haven't been able to reproduce in other projects (created with more recent templates)
