Hello,
Welcome to the Microsoft Windows Community.
Good afternoon. If you have a laptop, check if the Bluetooth toggle is turned off; it is usually activated by pressing a key combination like Fn + F (F1 through F12, looking for an antenna or Bluetooth icon).*
If it is enabled, press Win + I -> System -> Troubleshoot -> Other troubleshooters -> Bluetooth.
Follow the on-screen prompts, restart your computer, and let us know the result.
