Hi @jonathanpeppers, do you have thoughts on this one?

I'm curious about in debug within vs #24802, it doesn't crash. Let me try if it will crash if publish using debug mode.

Additional info for publish debug app: App will crash after 3 time to do : new 100 windows, then close all. Situation better then Release mode, but not better, due to my laptop has 50G Ram, but debug app will crash in about 400M . Also updated this info to the first description.
