Managing profiles and sync in Microsoft Edge on Windows 10
Microsoft announced a good while ago they were deprecating Collections in the Edge browser, they advised everyone at that time to backup their Collections to Favorites, I do not think that option is available anymore, your collections may still be available on this link: https://bing.com/saves.
They provide full details on that change on this link.
