9**Reason for Change**

11The Ability Assistant tool is the bottom-layer dependency for debugging capabilities of DevEco Studio. Normally, DevEco Studio restricts debugging of applications in release mode. However, there is a risk of bypassing DevEco Studio and directly using the debugging commands of Ability Assistant for debugging. Therefore, this behavior must be fundamentally restricted.
