[Bug]: During benchmarking, the offload model can lead to crashes.

(I used translater)

Regardless of what model I load, when it is being benchmarked and the offload model is enabled in the models interface, it will cause the software to crash.

Expected behavior

The benchmark should be forcibly stopped, and the model should be offloaded normally without causing the software to crash.

Environment (please complete the following information):

• Device: HUAWEI MBR-W39(Matepad Pro)
• OS: Harmony OS 4.0.0 (Android 12)
• App Version: 1.6.7(46)
• CPU：Qualcomm® Snapdragon TM 870 (8 cores)
