Windows 10 Hot Spot is not working?

I have a Windows 10 laptop (latest version of Windows). Today I wanted to turn on a hot spot on the laptop. If I click in the settings on the switch I get an error message. The internet works normally otherwise.

Could someone please help me there?

Sach not your laptop is over Wi-Fi on the Internet?

If your computer is on the Internet via Wi-Fi, it can probably not act as a hotspot on the same adapter.

Since the WLAN module can be used only once (you use it for the WLAN with you already) that will be nothing.

Why do you need a hotspot if the WLAN is connected to the Internet?

Otherwise, you need a different Internet access for the laptop, where the wireless module is just freely available.
