Nuendo with RME RayDat digital crackle noise after few minutes used

is anyone have similar setup with this problem ?
Nuendo and raydat last drivers updates.after few minutes of using it crackles’,and i have to do the reset button in nuendos studio setup to play without the noise for every few minutes.
when playing files with media player it does not occur.
win10, 2 raydat cards install.cpu and asio meter not overloaded

Please, don’t crosspost.
Also, note that Nuendo and Cubase share the same audio engine.

I’ll lock this one.
