I did as you said.The phone identifies the laptop now,and it also pairs.It shows as "connected" in bright blue.Blutooth icon on phone is white.
But,after 2-3 seconds,it turns into off color saying "not connected".Blutooth icon on phone is off color.
when trying to share from phone disregarding that,I was unable to scroll the list of devices.

Both blutooth settings on and visible,and I successfully shared a document even at last night too.But now,it doesn't work!
