Appreciate all the suggestions!!
 
Thanks mettelus for the testing. it seems that I still have the problem.
 
Cowboydan. I reinstalled graphics drivers, reset to default settings but nothing helped.
I will continue with my projects with a floating inspector and console and it's stable. Not the best workaround but at least Sonar then does not crash :)

Have you updated the Concrete Limiter and 4K Expander and 4K Channel Compressor to version 1.0.1?

+1  And if that is not it, I would also recommend giving Tech Support a call on this one. You have it pretty isolated to the console on a second monitor and the PC's causing it (which CW sells). I think they may be able to answer it more quickly.

Bumping this to see if there was ever a solution found??

Did you ever apply the X3 'E' update?

Featherlight appears to be new to this thread.
 
So in addition (standard advice) please check your drivers and windows update is up to date. 64 bit precision engine can be enabled as it is fixed. A VST reset may be required. Could be a dodgy plugin try creating a clean template for new projects.
Otherwise I suggest a new thread.

The e update fixed this issue. If you are still crashing after the update you need to contact CW. 

And you have not installed the x3e update because?

This is an old thread.
