PRIME Z790-P WIFI - Bluetooth does not work

[SviFi]

Did all possible driver reinstalls from Asus, from Intel, from Windows Update, from Armory Crate, does not help.

Windows 11 does not even show Bluetooth toggle.

In Device Manager, I see Bluetooth device appearing and disappearing by itself all the time. The event log shows errors repeatedly:

Device USB\VID_8087&PID_0026\5&cc3f949&0&14 had a problem starting.

Driver Name: oem90.inf

Class Guid: {e0cbf06c-cd8b-4647-bb8a-263b43f0f974}

Service: BTHUSB

Lower Filters: ibtusb

Upper Filters:

Problem: 0x0

Problem Status: 0xC00000E5

During the time when it disappears, in the General tab of the device, it shows the following error:

Currently, this hardware device is not connected to the computer. (Code 45)

To fix this problem, reconnect this hardware device to the computer.

Then after a minute, it goes to show "This device is working properly." But after another minute back to Code 45. And it repeats non-stop.

Is anyone else experiencing this? Is there a hardware issue?

The board was recently purchased and is under warranty, but I would very much hope to resolve this rather than deal with any kind of return.

Thank you!

You could try disabling Wi-Fi & Bluetooth in BIOS, rebooting and then enabling them again. This has helped other people with similar issues.
