Hi @Krish262 

Welcome to the HP Support Community.

Thank you for posting your query.

I understand that you see a Error Code 43 which means Windows has stopped the Bluetooth adapter because it detected a problem with the device. This is usually caused by a corrupted driver, Windows update conflict, power management settings, or a hardware communication issue. I would request you to please follow the steps:

Perform a complete power reset

• Shut down the HP laptop completely.
• Disconnect the charger and all USB devices.
• Press and hold the Power button for 30 seconds.
• Connect the charger and turn the laptop back on.
• Check if Bluetooth works normally.

Run the Bluetooth troubleshooter

• Press Windows + I to open Settings.
• Go to:
  System > Troubleshoot > Other troubleshooters
• Locate Bluetooth.
• Click Run.
• Apply any recommended fixes.
• Restart the laptop.

Reinstall the MediaTek Bluetooth driver

• Press Windows + X.
• Select Device Manager.
• Expand Bluetooth.
• Right-click MediaTek Bluetooth Adapter.
• Select Uninstall device.
• If available, check:
  Delete the driver software for this device.
• Click Uninstall.
• Restart the laptop.
• Windows should reinstall the Bluetooth driver automatically.

Install Windows optional driver updates

• Press Windows + I.
• Go to: Windows Update > Advanced options > Optional updates
• Open Driver updates.
• Install any available Bluetooth, wireless, or chipset updates.
• Restart the laptop.

Hope this helps, Please revert if the issue persists.

Take care and have an amazing day!
