@kant1 Here's a related post that has a solution to your predicament: click here to view,

And if that doesn't help, you may want to perform a hard reset using the below steps and get back to me with the results:

Ensure your device is OFF.

Unplug all the external devices (If any).

Disconnect the power from the computer

Press and hold the power button for about 30 seconds.

Connect the power supply

Press the power button to turn on your device and check if the issue persists.
