operational amplifier - Problem in using a buffered virtual ground as opamp split supply

The single-ended to differential converter on the right side works fine in sim only if I set opamp rails Vcc=12V and Vee=-12V as split supply. But if I supply the circuit by using 24V supply and a buffered virtual ground circuit as below it doesn't work:

I found the example usage of the BUF634 here:

What can be the problem?

Answer

NO idea what you mean by doesn't work.. Works fine here..
