[Problem/Bug]: Server connection issue with Sony websites

What happened?

WebView2 does not allow signing into sony.com, myaccount.sony.com, playstation.com, etc. which means the PS Remote Play App which uses WebView2 for sign-in fails to allow user verification.

By default, Edge will also block sign-in to these websites; however, other browsers work fine.
Opening a link from the sign-in page to the Sony site and trying to disable tracking prevention also does not allow sign in.

Importance

Blocking. My app's basic functions are not working due to this issue.

No response

Reproduce the failure in the PS Remote Play App using the listed WebView2 Stable Runtime and Windows 11 versions, following the nine sign-in steps. Compare the behavior across sony.com, myaccount.sony.com, and playstation.com, and document whether a connection can be established successfully without the reported error.
