Rendering Issue

I tried creating a black hole by following a YouTube tutorial . I did everything correctly. (Rendering format is Cycles). I tried rendering it, but it didn't came as shown in the render preview. While rendering this my laptop keep getting stuck and my project closes its own. I don't know why.

I couldn't take a screenshot in my Blender, so I took a picture in my phone. It shows that Blender isn't responding.

Keyframe Issue

I tried animating my black hole like original one moves. But in tutorial the black hole moves. Mine doesn't moves a bit. I add keyframes but it also didn't work. I tried it numerous times. When I add a keyframe for location in frame 1. And then I add a keyframe for location in frame 50, the whole location changes according to the frame 50.

I'm a beginner. Does anyone have any idea? I hope my question is clear.

This is the tutorial link:- https://youtu.be/XWv1Ajc3tfU?si=bu1Q65jztNGJ8D3M

My Blend File:-

I created this in Blender 4.1.

This is before rendering (render preview) This is before rendering (render preview)

    $\begingroup$ Use workupload and share the link, don't forget to pack the images (File > External Data > Pack Resources) $\endgroup$

    $\begingroup$ “I’m… following a YouTube tutorial. I did everything correctly.” No, you didn’t. Or at least, afawk the tutorial isn’t broken, because you didn’t link it. I suspect this is the reason for the question downvotes, because what’s the point of telling us you followed a tutorial, if we can’t see what they said to do (so we can’t debug based on it or see if they said something wrong) and you insist that you did what they said to do (so they must have said something wrong)? $\endgroup$

    $\begingroup$ Maybe share your file? ;-) It's hard to tell what's wrong just from the screenshots. Modifiers have different settings for viewport and render. You can also hide objects for rendering ("camera" icon in the outliner) and in the viewport ("eye" icon). As a result, the final render can look different from the viewport render. What is this checkerboard in the render? $\endgroup$

I can't reproduce the rendering issue. If your Blender crashed during rendering, have you tried following the crash troubleshooting guide in order to get any crash log or error message that could explain what's going on? If not crashing but just freezing, have you tried setting your end frame to 2 and run an animation render (⎈ CtrlF12) to see if with enough time it still manages to get the render done?

For the animation:

You have several "Spiraling" group nodes that create the spiral motion:

You can animate their values using keyframes or drivers.

Since each of them have a different value, i thought it would be nice to just "add" an animation on top of it.

I added a value node, clicked the value to edit it, and wrote #frame/100 which creates a driver using the current frame number divided by 100, effectively giving me a time animation. Then, after each Spiraling node, I added a math Add node, and plugged the driven value in the second slot.
