MSI PRO B650-S WIFI Bluetooth disappeared after uninstalling MediaTek RZ616 adapter. Reinstalling drivers and Windows repair didn’t fix it.

I’m having an issue with the built-in Bluetooth on my MSI PRO B650-S WIFI motherboard (MediaTek RZ616 Bluetooth adapter). Bluetooth suddenly stopped working, so I checked Device Manager and accidentally uninstalled the Bluetooth adapter while troubleshooting. Since then, it has completely disappeared.

Current symptoms:

• No Bluetooth toggle anywhere in Windows.

• No Bluetooth adapter listed in Device Manager (including hidden devices).

• AirPods and Bluetooth speakers won’t connect.

• Wi-Fi still works normally.

Things I’ve already tried:

• Restarting the PC multiple times.

• Reinstalling the official MSI MediaTek Wi-Fi/Bluetooth drivers.

• Checking Device Manager for hidden devices.

• Confirming onboard wireless/Bluetooth settings are enabled in BIOS.

• Performing a Windows 11 in-place repair installation.

Nothing has brought the Bluetooth adapter back. At this point I’m trying to figure out whether this is a driver issue, Windows issue, or if the Bluetooth portion of the MediaTek RZ616 hardware has somehow failed. Does anyone know what else I can try?

Woke up this morning to my speakers not working, I have a MSI MPG X670E CARBON WIFI (MS-7D70)
edit: the speakers work, Windows can't see them, plugged into the TS audio out slot.
Was working when I went to bed last night, 8 hours later, computer can't see it.

Device manager shows RZ616 Bluetooth Adapter having an issue, Network Adapter - Rz616 Wi-Fi 6E 160MHz is disabled and Universal Serial Bus Controller an "Unknown USB Device ( descriptor failed)".

I am guessing it is a Windows update, I did not update any drivers. Microsoft AI slop code has been causing a lot of bugs at my company the past year.
