The problem is that service WlanSvc cannot start. Error 1067. So, no Wi-Fi network is available: Windows doesn't search for Wi-Fi networks.
Killer(R) Wi-Fi 6E AX1675i 160MHz Wireless Network Adapter (211NGW). The adapter itself works fine, when I boot into another Windows Wi-Fi works fine.
I tried everything. The first thing I checked is if the adapter works. So, I used a Windows PE Flash drive, booted into another Windows and checked if I can connect to the Wi-Fi network. In that Windows Wi-Fi worked fine: Windows found all available networks and connected to one of them successfully. So, nothing is wrong with the adapter itself. It's something in my Windows installation. But everything, every step that MS gives about this issue ("Do network reset", "reinstall the drivers", "do the SFC check" (I did, nothing is wrong), "use network troubleshooter") cannot change the situation. The WlanSvc service gives no information in the Event manager but this: "Error 1067". I have no idea where to look for any information that may help to reveal what exactly is wrong with the WlanSvc service, what prevents it from working.

I apologize for the inconvenience and for not being able to resolve this issue directly.
Based on the information you've provided and the extensive troubleshooting you've already completed, this issue will need to be reviewed by the team that specializes in Windows networking services and Windows Insider builds.
Thank you for your patience and for providing such detailed information throughout the troubleshooting process.
Thank you very much for all your efforts. You were really helpful. You are the first person who has ever tried to solve this problem, so your help is very much appreciated. I even was able to find additional information about what is wrong with the WlanSvc service and I added this info to my first message. Of course, I added this info to my Windows Insider report too. Let's hope that it will have some useful consequences.
Does WLAN AutoConfig have the Startup type set to Automatic, and can its dependencies (such as Extensible Authentication Protocol (EapHost) and Remote Procedure Call (RPC)) start successfully?
Did this begin after a Windows update, driver update, VPN installation, antivirus installation, or network utility (such as Killer Intelligence Center)?
I updated my first message.
It started since Windows Insider build 29558. Of course, I reported about this issue in their Feedback Center, but there's no reaction there for more than 2 months already. So, I decided to ask about this somewhere else.
Can you try Safe mode with Networking?
In Safe Mode with Networking Wi-Fi and Bluetooth adapters are disabled. Only wired Ethernet is available. So, Safe Mode cannot help here. Fun fact: in Safe Mode the WlanSvc service works. It can be started, but since no Wi-Fi adapter is avaiable in the system, this service does nothing.
Hi! Let me help you.
Have you tried a hard reset?
Turn off the laptop.
Unplug the charger.
Remove all USB devices.
If the battery is removable → remove the battery.
Press and hold the Power button for 30–60 seconds.
Reinsert the battery (if removed).
Plug in the charger.
Turn the laptop on.
Yes, I tried that too. As I already mentioned in my first message, the first thing I checked is if the adapter works. So, I used a Windows PE Flash drive, booted into another Windows and checked if I can connect to the Wi-Fi network. In that Windows Wi-Fi worked fine: Windows found all available networks and connected to one of them successfully. So, nothing is wrong with the adapter itself.
