Nuitrack SDK crashes Unity applications after running for an extended time

Good morning,

we use the latest version of the nuitrack sdk for unity. While it works great most of the time,
we noticed that our application crashes after running for a few hours (exact time varies with each run)
with the following exception:

Perhaps the sensor is already being used in other program. Or some unexpected error.
nuitrack.Exception
at nuitrack.NativeImporter.throwException (nuitrack.NativeImporter+ExceptionType type) [0x00096] in <0dba52d8ba4c458ab12d583e381918b5>:0

at NuitrackManager.Update () [0x00043] in <242d4c02e8ee42e4945e66ce965d436c>:0

is there some way we can avoid this exception, or recover from it without having to restart our application?

Kind regards,
Nicholas
