I assume you are building your project for iOS devices. If so, with the latest AppBuilder release, we introduced a regression in the iOS LiveSync feature. Its behavior is the same as the one you have explained. We expect to release a fix for this at the very near future. However, until then your only option in order to prevent this, is to disable the LiveSync
when deployed on actual devices or to build your project in Release mode.
Please, excuse us for any inconveniences caused by this. Thank you for the understanding.
