I'm sorry for the inconvenience.
According to your description, it is normal for Lele Security to have the option of not applying freeze, and then the operation was cancelled. You can go to the PC music assistant to try the corresponding freezing operation. It is not recommended to freeze the pre-installed program that comes with the system, and Le 'an Quanyou does not support freezing.
If the corresponding program cannot be frozen, it is suggested that you can update the version of the music assistant on the PC side before using it. At the same time, it is suggested that you can back up your mobile phone data and restore the factory setting operation without sending it for repair.
