Generative AI model picker is blank in the Contextual Task Bar (v27.6). When clicking to 'Choose a model,' the selection window opens but remains empty with no available models (Firefly/Gemini/Partner models) appearing in the list.

Since updating to Photoshop Beta 27.6, the model selection interface in the Contextual Task Bar has become non-functional. While the 'Choose a model' dialog box triggers and opens correctly, the selection pane remains entirely blank, failing to load or display any available AI models (Firefly, Gemini, or Partner models).

This is a persistent regression; the feature was fully functional in previous beta version, current version : Adobe Photoshop Version: 27.7.0 20260415.m.3506 55a492a  x64 (beta, PublicBeta)
