Thank you for following up! I’m going to amend the issue to reflect that the problem is now in launching the package after installation. Now that you are able to package, are you experiencing something similar to this user? Cesium content not working on Hololens 2
I suspect we are going to need to do more testing to be able to figure out the source of this problem, and we may not be able to get to HoloLens testing immediately. In the meantime, if you encounter any similar issues or find an error message, please add them to the Github issue as well.
Thanks again,
Alex
