Stepper Motor is juddering - controller issue

Hi there,
out of nowhere my x axis stepper motor is not working anymore.
I have a Ortur lasermaster 2.
I have replaced the stepper with a new one, same issue.
As I restart alarm 9 appears, as he is not able to get to the x-home.
The stepper is doing very loud noises and is moving very slow and shaky.

What might be the problem?

I have tried a lot:
checked all my cables
changed the cable with the y stepper - y stepper has problems then/is juddering
so my suggestions is: the comments going to threw x axis cables are somehow wrong?
anything I can try to fix this?
I updated my LightBurn today

You may have a bad stepper motor driver or bad connection. With power on I would try and move each axis by hand. Should be difficult to move if good. Also there maybe leds on the driver boards inside that will tell you if they are getting an input signal. Blinking when active.
