When I click "Choose a default" in Settings and then pick a browser nothing happens.
I've even tried editing the Registry directly and setting the values there, and windows still defaults to Edge.
I even have a video: https://www.youtube.com/watch?v=YbYxU5Waz0I
This registry key is already set, to zero effect:
[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\Shell\Associations\UrlAssociations\https\UserChoice]
"ProgId"="ChromeHTML"
