iMac (Retina 4K, 21.5-inch, 2017) will no longer connect to WiFi

My iMac (Retina 4K, 21.5-inch, 2017) will no longer connect to WiFi. I can connect to the internet with an ethernet cable without anyissue. But I can't connect to WiFi at all. When I open Network Preferences, it won't even allow me to Turn WiFi on.

I have run Disk Utility numerous times and everything always checks out fine.

Any ideas? Thanks!

Put Wi-Fi in the top position and turn Wi-Fi on. If that does not work, restart in Safe Mode and then reconnect to Wi-Fi.
