Bootcamp/Bluetooth not working - can't see "Apple Broadcom Built-In Bluetooth" in Device Manager

I have a MacBook Pro 13 (2017) - just installed Bootcamp...windows not working...went through the various forums on the topics. and reinstalled all the latest driver packages. If I turn off the computer fully, the computer will connect to the bluetooth mouse or headphone, but it will not work....1) contrary to other issues I have seen in forums, I can't see "Apple Broadcom Built-In Bluetooth" in Device Manager, so I can't install the specific drivers. 2) Also in Network Adapters/Boradcom 802.11ac Network Adaptor, the version is 7.35.118.83 and there not possibility to enable Bluetooth Collaboration. Any suggestion?

This is from an 2014 iMac, very similar to your MBP.

In Windows Device Manager, click on View -> Show Hidden Devices. Do you see the BT card?

You can install 7.35.118.73 or older driver. Also, what is the PID/VID of the BT hardware in Windows Device Manager?

This is the Network card. On the macOS side, click on About This Mac -> System Report -> Bluetooth and post the PID/VID.

You will also need to look at Power Management settings. You do not want Windows to turn off BT devices to save power.

This is for Network devices. You need to check the same for Bluetooth Radio.

This is what I see if I show hidden devices.

Also I installed 7.35.118.73 version and enabled collaboration and disallowed power management. Same thing...bluetooth will work for 30 secs and then device does not respond although system says it's connected.
