Vuforia Studio - How to enable "allowEmpty" option?

Hi @DD_10645209 ,

never heard this option but if this is an option suggested by Studio error logging - then the only place it think is to set in the Studio builder-settings.json in the VuforiaStudio directory in the Windos document folder. Stop Studio . Backup the old version. Add the allowEmpty: true example:

 },
 "enableDebugLogging": true,
 "welcomeDismissed": true,
 "designTimeDropShadows": "HARD",
 "projectsListView": true,
 "allowEmpty":true
}

If this not work so possibly you can try ans OS windows enviroment variable set allowEmpty=true but I do not believe that this is an OS variable

Another point is to use the current Studio Version which will not update automatically. You need explicitly to download form the PTC Web Side https://support.ptc.com/appserver/auth/it/esd/product.jsp?prodFamily=VFS

So if the mentioned points above are  not helpful - create a new project and replace the <View>js and <View>.json e.g. Home.js and Home.json - from the source project folder with the old one. and also copy the the Application style defs with app.scss 

Copy the data with the upload folder.

If other customer data is in the project then you need to copy this data also to the new project folder. This means we create a new project and overtake all data from the old project which is corrupt.
