Garmin Venu kept on updating but restarting, heart rate and pedometer doesn't work too

It seems there is no more menu for just the VENU, not VENU  2. I am having recent issues with my VENU where it does not read the steps and heart rate. Green sensor does not light up. I reset it to factory settings already. Updated the version using Garmin Express. Current software version is 8.0. GPS version is 6.0. WHR and Sensor version is 0.0. BMX 0.0. API level 3.3.6. secondary BMX 0.8.0. Connect IQ System 5. TSC Version 2.12. WIFI version 4.01. ANT/BLE/BT Version 8.02. It said update and i did but it just kept on restarting. i dont know what to do anymore...
