USB Debugging

I unlocked the developer options, but the USB debugging option is greyed out. I can't select it.
I tried restarting my phone in safe mode but this didn't help.

Try plugging in your phone to a computer before trying to toggle the debug option

Uninstalling Knox finally fixed it for me.
