My lightroom classic does not recognize my GPU (RTX 5090)

[LAW37341902nt28]

Hello.

I've just upgraded my Graphic card from 5080 to 5090.
I had my graphic drivers delete and updated.
and I have uninstalled Lightroom classic and re-installed it.

and still it does not recognize my RTX 5090.

In preference setting, Camera Raw graphic acceralation tab is disabled(it's grey and unable to select anything probably because it does not recognize my graphic card)
I've tried deleting preference files and everything but I can't find how to make it work!
I've used acceration just before upgrade when I used 5080.
Does anyone know what's the issue is all about?
