Question fastboot command not working | waiting for any device - OnePlus Nord 2 5G

Hi all,
first of all: yes, I've used the search function but I couldn't find a solution.
I have a Nord 2 5G device and want to install Evolution X Custom ROM.
I followed the instructions in this forum (and other websites) and managed to downgrade to OOS 11 in order to get into fastboot. The adb command to boot into fastboot mode also worked and my device is saying
fastboot_unlock_verify ok
The device is in fastboot mode which is only for debug Android devices. If you want to exit fastboot mode, please long press volume up and power buttons simultaneously.

However, the fastboot command to flash TWRP does not work. On the command line I can only see
< waiting for any device >
Click to expand...
Click to collapse
and I continuously hear the Windows device attached/device detached chime. The device manager shows this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After opening the properties, I can see this:
As it's German. It says:
The drivers for this device have not been installed. (Code 28).
There are no compatible drivers for this device.
Click to expand...
Click to collapse
So obviously I need additional drivers. I have downloaded the USB drivers from this website: https://developer.android.com/studio/run/win-usb, chose install from hard drive and pointed to the directory I have unzipped the driver set but Windows can't install them. I have also downloaded the OnePlus driver set from https://oneplusdriver.com/download-oneplus-driver and installed them.
Still, it doesn't work.
I am at the end of my rope now. What did I do wrong?
Thanks in advance!

Have you try to use platform-tools? It has adb and fastboot. I have always used that and no problem
SDK Platform Tools release notes | Android Studio | Android Developers
Android SDK Platform-Tools is a component for the Android SDK.
developer.android.com

Look in Eigenshaften > Details > "Device instance path" (k.A. Gerätepfad?).
What's the VID/PID?
Is that in the stock INF file in android_winusb.inf?
If you want, you can just use Zadig drivers. I can give you "fastbogus.exe".

Select "WinUSB".

Yes, the thing is, I've installed the drivers in the wrong way. I'll try to give a step-by-step guide:
Go to Device Manager and find the Device (will have the yellow triangle. Right-click on it and choose upgrade driver (hope that's what's shown in the english version of Win 11). You'll see this:
Click the second option. You'll see this:
Here, choose the second option at the bottom. That's where I did it wrong. I selected the drivers in the dropdown menu and that doesn't work.
Click there...
and click there to select the diver *.inf file in the usb_driver folder.
That should work. It's important that you use the official Google Drivers (at least it was important here).
Hope that works.

Hi,
I managed to install the ADB google drivers so I can now at least see Fastboot devices response properly but I do not know how to unlock the bootloader as the command "fastboot oem unlock" is not recognized and there is still no menu for the bootloader unlock (only the message on the black screen)
If anyone could help I would be be very grateful.
Thank you.
Best Regards
