Bluetooth just randomly disappears?

Hi,

I was on my laptop listening to music connected to my headphones through Bluetooth, and it just randomly cut off. Seeing this, I tried reconnecting and found out there was no longer an icon for Bluetooth devices in my taskbar.

My device is an Acer Predator 15

My headphones were SONY-10000XM3

I tried finding Bluetooth in various places, services.msc (the Bluetooth service was there) but I did not find it at all after clicking show hidden devices in Devices.msc. Something called "Qualcomm Atheros Bluetooth installer" was also still present when I
searched "Bluetooth" in Programs

I've also tried restarting after the incident, but nothing. It was like all of Bluetooth and its drivers just vanished.

Any clue to what has happened? It just randomly disappeared. This was also a recent windows update.
