Need help regarding Differential Pair Routing on PCB Editor 17.4

Hi
I'm a newbie, I need suggestions regarding differential pair

I have completed most of my routing on a 4 layer board and not routed the differential pair which I had kept it later to route, but now I'm unable to route the differential pair according to the rules of the differential pairs of USB,Ethernet and CAN protocols as all the above protocols should get reference plane and there should be no single trace passing under the differential pair, but as I have already routed there are many traces which are getting crossed over in different layers.

How can I move forward?

Please suggest

    Hi, if you are out of routing space and time is not on your side just move that 4lyr board to 6lyrs instead.

    There will be a minor cost incursion in volume for a 6lyr board, however from an electrical perspective it should work better as you have more surface
    area  to work with. With the extra layers your power distribution should be better too.

    Best regards.
