Pen Cursor invisible without driver [Windows 10]

Hey, thanks for reaching, I have my Huion Kamvas 12. you might know, if you operate the pen without the driver, a tiny small circle appears on screen, but now it's kinda invisible, like the tiny small circle dont appear, then I un installed the driver, and restarted the pc, then the problem fixed but it's again started :) . why this happens :)
