Following up here regarding FB18350039, this morning without any code changes it is working as expected, is the team working on this issue as a permanent fix or should we just disregard this issue as an upcoming beta fix of some sort. Thanks.

Hi DTS Team, I am encountering this error as well. Most recently my demo app was working as expected on the simulator running macOS 26 beta on a mac Mini (using the internal drive, not VM or external), however now I am getting the following inferenceError: InferenceError::inferenceFailed::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} Here is my Feedback ID which contains the sysdiagnose from my mac Mini: FB18350039 Thanks for helping us resolve this issue.

Hi Abhi, I'm curious was this issue resolved for you, a few days ago it was occurring with my build but seems to have been resolved by Apple.
