RenderScript: Unable to open shared library: (null)

I wrote a simple application that uses RenderScript to change the camera's preview. There were no issues with other devices except Honor 6X and Nexus 6p both with Android 7.0 where the camera preview only shows a black screen.

The error messages are as follows:

V/RenderScript: Successfully loaded runtime: libRSDriver_adreno.so
E/RenderScript: Unable to open shared library (/data/user_de/0/com.my.test/code_cache/com.android.renderscript.cache/librs.invert.so): (null)

My RenderScript file is also the same as to: https://developer.android.com/guide/topics/renderscript/compute.html#writing-an-rs-kernel

#pragma version(1)
#pragma rs java_package_name(com.my.test)

uchar4 RS_KERNEL invert(uchar4 in, uint32_t x, uint32_t y) {
  uchar4 out = in;

  out.r = 255 - in.r;
  out.g = 255 - in.g;
  out.b = 255 - in.b;
  return out;
}

EDIT:

The camera preview only shows a black screen on the mentioned devices.

This is not an issue with RenderScript rather with the Camera or my implementation, see Camera onPreviewFrame not called on some devices as I have found out that some devices do not call the onPreviewFrame which led to this issue.
