Internet sharing disabling Macbook Wifi

So I wanted to share the Ethernet connection through my Wifi to my phone, since it is having problems connecting to my router at home.

My Wifi works fine on it's own. My ethernet connection works fine on it's own.

But when I plug in my Ethernet connection and turn internet sharing on it disables my wifi. When I try to click "Turn on WIFI" nothing happens.

As you can see in the top right corner the Wifi is disabled and I can't enable it.

After the Internet sharing disables my Wifi I need to turn off internet sharing and restart my macbook for the Wifi to switch back on again.

Does anyone know why this is the case?

I have tried looking for alternative hotspot software for mac, maybe this will solve my problems but couldn't find any of those either.

I was also scratching my head just to share my one iPhone internet to tether via my iMac. It was so silly what solved the problem.

Uncheck the internet sharing checkbox in sharing system preferences. After unchecking the internet fields were enabled.
