in Fusion

As title indicates, I'm suddenly experiencing an issue in my Unity project where my spawnable prefabs are not populating the Prefab Table and show as Null in the Prefab Source (Network Object).

I've tried removing and re-adding a new network object component to the prefab. When I click Reimport, nothing happens and if I reopen the prefab, it reverts to the Null source (see screen captures below).

I'm not seeing any errors.

I've also tried updating to latest version Fusion SDK 1.1.3 Nightly Build 594 with no luck.

Has anyone ever experienced a similar problem and if so, managed to resolve it?

    Nevermind, issue is resolved.

    It was caused by a missing reference in Addressables Groups, which was tripping up Fusion.
