use my own cti in HALCON, can not capture image

[QTSXZ127]

Hi there,
I referred to GenICam_GenTL_Webcam and wrote my own cti with a ToF camera (https://vzense.com/).
The cti work well with rc_genicam-api and can capture images successfully.
However, when integrated it into HALCON, it can just manipulate camera parameters, can not capture images.
By looking at printed information, the cti can retrieve images from the camera.

If you have encountered similar problems, please give me some help, Thanks.
