I see no alternative if the start is in step 4 (maybe in your case you started in a different place):

Going right and down, then the cyan cube is placed in your step 3 and can't be moved.

Going down and right, my steps are like yours, but the cyan cube is moved to the right and the result is different.

The only solution I see is what I shared in my previous comment, and it should work because I solved other puzzles in a different way compared to you, but with the same result, and the achievement was unlocked. So it seems that this achievement is broken now.

Steps 1 and 2 are over-written by previous steps. You'll need to work out how to get to 4 based on where you start. This image is ~6 years old. I have no idea if anything has changed, and I cannot help you.

If you start in cell 4, how can you do it that way? where are step 1 and 2? I have done it in a different way but with the same result and the achievement is not unlocked
