Hello.
Thanl you for your workaround really fixed. Now I can turn on hotspot.
But I cant connect other devices to it. My phone and other devices are
seeing this hotspot but when I enter password, it simply goes to "saved"
state in phone and in other laptops it take time and goes to nothing.
my `journalctl -u NetworkManager` is attached.
