CUE BUTTON sometimes doesn't work and traktor crashed twice.

the cue button sometimes doesn't work, it's not a problem with the console but with the traktor program, if I press the button with the mouse it still doesn't work. When the cue button is set at the beginning of a loop, in addition to not working, the track skips to the end point of the loop. In these cases if I press the corresponding cue point in the pad section the cue point works. Also, sometimes Traktor crashes completely without any messages coming through.

I tried updating Traktor, updating OS, writing to Native Instruments but nothing worked.
