    Issue with wifi and bluetooth in dualboot laptop (Windows 10 + Ubuntu)

    Dear community,

    I dualbooted my laptop with Ubuntu and there are 2 issues with this setup. I am not sure whether these 2 issues are related to each other or not.

    Code:
    Model : HP laptop 15s - du0xxx
    BIOS  Mode: UEFI
    Wifi Adapter: Realtek RTL8723DE
    Network settings: https://pastebin.com/d5L9pWmL
    
    Issue 1:
    I can access my Wifi when I am logged into Ubuntu but Windows cannot even sense my Wifi adapter.
    When I troubleshoot the problem in Windows, it resets my network adapter/driver (after which I have to reboot the laptop) and then I can again use it in windows.
    Unrelated fact : The date and time of my system in windows goes out of sync every time the adapter fails.
    Note : The issue with windows doesn't occur if I do not switch to Ubuntu. The network adapter connection fails only after I have logged into Ubuntu. Also, Ubuntu always connects to the wifi without any hassle.

    Issue 2:
    Ubuntu cannot sense my Bluetooth adapter/driver. It doesn't even allow to me to toggle the bluetooth switch in the settings page. It says "No bluetooth found. Plugin a dongle to use bluetooth".
    But I can smoothly use bluetooth through windows.
    I ran the hcitool dev command in my Ubuntu terminal and it found no devices.
    I also searched additional drivers in Ubuntu but it could not find any.

    Another weird issue : When I boot into windows from Ubuntu with restart (not complete shutdown) then it takes around 2 - 3 minutes for windows to start up. In comparison it takes around 5 - 6 seconds to boot up Windows from complete shutdown.

    Thank you for your time.

    Update 1:
    TL;DR : Switched on the network adapter toggle in BIOS settings but that did not solve the problem. But now the grub loader gets bypassed.

    I opened up the BIOS settings and saw that the option of network adapter was disabled. So I enabled it. But now the GRUB boot is completely bypassed and windows is getting loaded automatically.
    To revert this, I again disabled the network adapter in my BIOS settings but the GRUB boot option is still getting bypassed.
    So, first I managed to get back the GRUB loader my writing the following command in command prompt of windows.
    Code:
     bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

    This worked for the 1st time but now even if I use this command the GRUB loader gets bypassed.

    Update 2:

    I downloaded a bluetooth manager on Ubuntu but it gives the following message :
    Connection to BlueZ failed. BlueZ daemon is not running, blueman manager cannot continue. This probably means that there were no Bluetooth adapters detected or Bluetooth daemon was not started.
    It would be really helpful if someone can give a detailed solution to the problem or else I will manage to make things worse like this.

    Update 3:
