After installing driver version 430.14 on a RHEL 7.6 system with kernel 3.10.0-957.12.2.el7.x86_64 the X server dies after a few seconds.
I think these are the relevant lines from Xorg.0.log:

Card is a Quadro P4000 with an attached NVidia 3D Vision set.
Since user needs to work with it I switched back to 396.54 so I cannot run additional tests right now.
We have another machine where 430.14 works with the same kernel. Differences are: different card, different Monitor, no 3D.
