Bootcamp stuck at Download Window Support Software

I'm using Imac27" Late 2014 early I use Bootcamp to install window10 the process is all work.

But today I reinstall window10 again because I want to play some games that can't play on macOS so I am stuck in some issues like when selecting Window10 Iso It does not have the Partition part show up I think it will show on the next step but yea... I am stuck at Task Status: Download window support software for 2-3 hours I think this is not right cause early it seems like 30mins or 1 hour like that it does seem not to take too much time like this.

So what can I do to fix this
