A poorly Cytisus Racemosus

Hello there, I have a very well established Cystisus Racemosus which turned itself into a beautiful tree. However, it has not enjoyed the weather we have all been experiencing. It’s the first time I’ve seen it shed it’s leaves and looking on the dead side. However, on doing a bit of scraping on it’s woody trunk, it’s still very green underneath, and the branches are green underneath. I can’t see any new shoots anywhere, but can’t work out if it’s on it’s way out, has anyone experienced the same, and if so, any top tips?
Many thanks
Suzy
