Please try the following:

1. Go to Settings> Network & Internet> Internet> WiFi, and toggle the WiFi switch.
2. Turn Airplane Mode on and off, and turn the WiFi switch on again.
3. Restart your phone and try to turn on WiFi normally.
4. Back up any important data and restore your phone to factory settings.
