NX11 existing with FATAL error while on coming out of screen locked session

Hello experts

any one encountered issue where NX11 is crashing out after you lock your computer for an Hour or Two and unlock the computer

This happening on HP Zbook desktop

This is not repeatable, but happening quite a few times for few users.

Few of errors that i could find in NX syslog are

>>>> Error code 3070022 caught in file "o:\ugnx1102\ip7\src\interop\no\ind\interop_manager_definitions.c" at line number 110

Not much ifnormation i could gather, expet that Graphics driver

Current NVidia Driver is 21.21.13.7563 = 375.63 is a bit older than the CERTIFIED driver from GTAC list 385.69 l. They had NX9 earlier with No issues
