One would expect that reverse engineering technologies wouldn’t be impossible.
The importance of these technologies for China is huge.
Moreover, they have a massive budget and probably also own a couple of ASML’s euv lithography machines.
Why is it that they cant remake these machines?
I heard some sources say that it might take them a decade.

The machines that ASML make aren’t made from scratch by ASML. They source highly specialised parts from other companies who often only exist to supply those specialised parts.
As an example the mirror surfaces used by the EUV machine are specially made by Zeiss, who are a world leading optics company. So reverse engineering also involves reverse engineering that whole mirror process as well
