Maybe it is a memory issue again, because the error code 0xc0000409 seems to denote corruption of the stack. (Sometimes it has other meanings). Are you using some native or third-party components?

I have not used any native code or third-party components. I have added code for unregistering the events added to the controls in the Unloaded event of the page. If i comment those code, app works good. if i uncomment those codes, app crashes with above error.

Based on your description, it seems that you will create controls when you navigate to the target page. Every time when you navigate to a new page, it will create a new page instance. So this might be a memory issue again. I'd suggest you check the memory usage as well.

If this is the reason, a quick workaround is to enable the NavigationCacheMode property of the page. It will reuse the page when you navigate to it.

Hello,

Welcome to Microsoft Q&A!

The Error Description for 0xc0000409 is The system detected an overrun of a stack-based buffer in this application. This overrun could potentially allow a malicious user to gain control of this application.

This seems to be a might be a memory issue again. Based on your description, it seems that you will create controls when you navigate to the target page. Every time when you navigate to a new page, it will create a new page instance. This might leads the raise of the memory. I'd suggest you check the memory usage as well.

A quick workaround is to enable the NavigationCacheMode property of the page. It will reuse the page when you navigate to it.

Thank you.
