I have the same issue, and its driving me mad.
Notifications will open a Chrome tab only if Chrome is already open.
If Chrome is not already open then the Notifications just disappear after being clicked.
Also now the time to disappear is being ignored and the Notification now stay on the screen indefinitely.
I can confirm the latest build is installed and windows updates confirms no updates available.
Chrome is also updated, also I have tried reinstalling Chrome and the same issue persists.

Intel 17 7700
