Thanks for reaching out. I've assigned this to a dev that can help follow up on this.

@q71114 Thank you for the feedback. This issue has already been fixed in version 111.0.1661.51. You can try updating the runtime and trying again. In the new version, this download is considered unsafe, so it will not be downloaded immediately. After clicking the '...' button, select 'Keep' to download the file. By reading this document mixed content downloads,you can learn about the reasons why the download is being blocked.

Thanks @xu-ms for the update. I checked the changes and it looks good, however there are a few bugs:

• The confirmation dialog has a Learn more link
• When clicked on the link an Edge popup appears with its own icon in the taskbar instead of triggering NewWindowRequested event

• When Report this file as unsafe option is selected an Edge popup appears with its own icon in the taskbar instead of triggering NewWindowRequested event

@q71114 The link here looks very unusual, I am not sure if this is by design or not. I created a bug internally to investigate further, and I will update you on the progress as soon as possible.

We also see a similar issue: When canceling and then retrying a download, we can click on that download to open the file, but instead of the NewWindowRequested event being raised, the file just opens in the default Edge/WebView2 popup window described above.
