Add Shortcut to Files fails

In my case, it is even worse.

OneDrive Shared Folders No Longer Sync to File Explorer.

Shared folders in OneDrive Personal accounts no longer sync directly to File Explorer, even when both users have Microsoft 365 Family subscriptions and active OneDrive desktop apps.

Previously, when someone shared a folder via OneDrive, the recipient could click “Sync”, and the folder would appear in File Explorer — fully integrated, offline-ready, and easily accessible like any local folder.

Now, shared folders only appear as shortcuts (via “Add shortcut to My files”), and:

They often fail to add (e.g., “1 shortcut wasn't created” errors),
Or they add as web links that open in Edge, not folders synced via the OneDrive app.
EVEN doing that, my Microsoft Edge remains blinking for some reason. See the screenshot below. I restarted the browser, the PC, everything. I have plenty of space. And I am sharing a folder with my wife, as some of you.

This is frustrating beyond the early days of raw open-source and low-quality options available in the early 2000s.

If a family subscription cannot share a folder anymore, the whole family subscription loses its sense.
