Have been struggling with this issue for almost a year now. Have tried driver updates and several suggestions from other users with no real success.

To solve the issue, I have to power down the computer by holding the power button. Once the computer is powered up, i accept to restart the pc, (not the message that says windows was not shut down correctly, must windows repair),

After searching around in device manger, i found the following solution which solves the problem, but i am unsure how to make this selection permanent in windows, here goes,

Press Windows  Start button > select Settings > Select System>  Select About> Select Device Manager (right side of screen)> Once Device Manger is open, expand Human Interface Devices > Select Bluetooth  Low Energy GATT Compliant HID Device> Right Click > Properties> Open Power Management Tab> Uncheck - Allow the Computer to turn off this device to save power > press ok

This resolves the issues of the erratic behavior
