ADB "error: protocol fault (couldn't read status message): No error" when pairing over wifi

Question

I'm trying to connect my Android device via Wifi to adb by using the 6 digit pairing code.

On my Android device phone I enabled wireless debugging and clicked on "Pair device with pairing code". In the Windows 10 PowerShell I try to connect by running adb pair <IP>:<port>, this is the output (it loads for some time after entering the code):

adb pair 192.169.0.99:46351
Enter pairing code: 393041
error: protocol fault (couldn't read status message): No error

I'm running Android SDK Platform-Tools 35.0.2

When connecting via QR code in VS code, there's no problem, so I don't think it's a network issue. I already tried:

reconnecting phone and PC to the Wifi
Restarting the adb process with adb kill-server and adb start-server
Updating all Android SDK tools
Making sure the adb port 5037 is not occupied by a different process
running netsh interface portproxy reset

What device model is your Android device and what Android version is running on it? — Robert

May be logcat log from Android device contains an error message that explains a bit what is going wrong. Therefore I would recommend to first connect the device via USB adb to the computer, start adb logcat and then start the adb WiFi pairing process. — Robert

I got the same problem, you have to enable both USB debugging and Wireless debugging, turning on only usb debugging wont work....

I did that, otherwise I wouldn't have been able to connect via QR code.

As for me disabling "Random mac Address" in the mobile device's wifi settings solved the issue.

It could be beneficial to explain how to do that or at least link a guide
