Accelerometer randomly stops working?

I am a new user, the graph is attached

, The phone is oneplus5, I have sent the report from the APP( Sleep Crash report - 20211216 (22587) 27 [Manual error]),and I received the return mail , but it can’t solve the problem.

Can anyone help me?

Maybe your phone uses an aggressive way to save energy and turns off the bluetooth connection. Check if you have disabled battery saver for SaA.
