The issue mentioned below has now been resolved with the release of Vuforia Unity Extension v9.7.5:
Please see our release notes for more details: https://library.vuforia.com/articles/Release_Notes/Vuforia-SDK-Release-Notes.html
Thank you for your interest in Vuforia Engine!
Vuforia Unity Extension v9.7.4 is not able to load Area Target datasets created with the Vuforia Area Target Creator app, as well as datasets from Matterport scans generated with the Area Target Generator. Our team is aware of the issue and working towards resolution.
Current recommended workaround is to use Vuforia Unity Extension v9.6.3 when working with these types of Area Targets. To roll-back to that version of the Unity Extension, please refer to the following documentation.
Stay tuned for updates, and apologies for any inconvenience.
