Thank you for the confirmation. The fact that Bluetooth only shows as .inf files (e.g., oem59-67.inf) and no actual device appears, even with hidden devices shown, confirms the system isn’t detecting the Bluetooth hardware at all not even as an unknown device.
It's possible that Bluetooth hardware is:
-Disabled in BIOS
-Not initialized by Windows
-Physically failed
Let's try to do a BIOS reset.
Power on your PC and press Del repeatedly to enter MSI BIOS
Once in BIOS, press F6
It will ask to "Load optimized defaults?" — select Yes
Press F10 to Save and Exit
Let's also check if there are services that's conflicting with your Bluetooth drivers.
Press Windows + R, type msconfig, and press Enter.
In the System Configuration window, go to the Services tab.
Check Hide all Microsoft services, then click Disable all.
Go to the Startup tab and click Open Task Manager.
In Task Manager, disable all startup items.
Close Task Manager, then click OK in System Configuration.
Restart your computer.
