When I opened the settings page again, it would show that the mouse was connected and start moving again. The issue was that when connecting a Bluetooth mouse to the newly formatted Windows, the mouse would respond when I had the Bluetooth settings page open, but would become unresponsive when I closed it. Note that I did completely get rid of the macOS partition this time around, but did download the latest Boot Camp drivers prior to removing macOS completely. Recently I had to re-format my dad’s Macbook Pro 2017 13-inch model with Windows 10 and faced an issue I never faced before when installing via Boot Camp.
