Strange, I've activated Siri, which triggered some downloads and now it works again. Nevertheless, it will be interesting to get a reliable recovery way, because I've tried this also previously and it didn't help

Hi, my first post here. I have the same issue since today morning, till yesterday everything was working properly. I am on: macOS 26.2 Xcode 26.2 Tried now also with the FoundationModelTripPlanner and getting: Passing along Model Catalog error: Error Domain=com.apple.UnifiedAssetFramework Code=5000 "There are no underlying assets (neither atomic instance nor asset roots) for consistency token for asset set com.apple.modelcatalog" UserInfo={NSLocalizedFailureReason=There are no underlying assets (neither atomic instance nor asset roots) for consistency token for asset set com.apple.modelcatalog} in response to ExecuteRequest Received ModelManagerError that couldn't be converted to a TokenGenerationError: Model Catalog error: Error Domain=com.apple.UnifiedAssetFramework Code=5000 "There are no underlying assets (neither atomic instance nor asset roots) for consistency token for asset set com.apple.modelcatalog" UserInfo={NSLocalizedFailureReason=There are no underlying assets (neither atomic instance nor asset roots) for consistency token for asset set com.apple.modelcatalog} Failed to fetch model metadata.
