iCloud Device can not be added

I have added several items from my iCloud account which works quite stable and reliable.
Now with every new device I’d like to add gives me the following error on the UI
ERROR: 409 - Conflict
and in the log
[ERROR] [home.core.thing.binding.ThingFactory] - Thing factory (class org.openhab.binding.icloud.internal.ICloudHandlerFactory) returned null on create thing when it reports to support the thing type (icloud:device)

Regardless if its an Apple Watch a New iPad Air, etc.

Did you try to restart OH?

Yes, several times since the error first occurred. Also cleaned the cache - nothing worked.
