Hello ,
We are making games using nuitrack and we have also completed.
When we output the executable from unity,
The game sometimes runs normally, sometimes it can’t open and send an error message appears.
the error display:

Kinmen [version: Unity 2017.4.27f1 (0c4b856e4c6e)]

SenDuck.dll caused an Access Violation (0xc0000005)
in module SenDuck.dll at 0033:9998dfbb.

Error occurred at 2019-11-21_172632.

Already have confirmed SenDuck.dll in the file, but the game error still can’t be found “SenDuck.dll”.

Our development environment is,
Windows 10
sensor : XTION2

We are in a hurry, I hope someone can help us.
Thanks you!
