Thanks for the report.
I can't duplicate the problem. Whatever face I pick immediately aligns with the build plate and the Z goes to "0".
This is with 5.8.1 on a Win10 Pro laptop.

Someone from the Cura team will take a look.

Thanks for repling,
When using my computer (run on windows 11) this problem gone, but appear in my laptop (also run on windows 11).
I had tried to use the previous version of Cura (from version 4), but it still didn’t work.

You could try re-installing Cura on the laptop. I wouldn't think it has anything to do with the video system, but it might.
Every once in a while (not often) this problem is reported, but if it is a Cura problem it hasn't been found.

re-installing didn't help, I tried many times! I think the problem is my laptop lol

Everything was fine in Cura but when I played with that model in MS 3D Builder I got an odd result.

I think MS 3D Builder is taking the Center of Gravity into account. The model would sit on that face if it was opened that way, but I could not get it to "settle" on that face on purpose. It always fell over.
