Failed to load tracker data

Since the last update I am not able to create new experiences anymore.

The old expereinces are working still fine.

I can create a new experience and view it Preview, everything just looks fine.

Publish does not give any problems or failures.

When I scan I can choose my experience, so the Thingmark and the experience is recogniced.

After a while I get this failure message.

Failed to load tracker data(1 of 1) First failed src is: vuforia=vumark://vumark?id=((thingworx:thing))

Any ideas ?

The only thing that was changed on my side was the Studio update
