solution:

I've been using this method for the past few fast ring insider builds and it never fails. the procedure is to make an ISO file for each build but of course it's all done automatically and downloaded Officially from Microsoft servers, this is just an automation script.

use this website: https://uupdump.ml/known.php
select your build number
select language and click next
select the right edition and click next
then click on "download using aria2 and convert"
after that extract files to a folder and run the "aria2_download_windows.cmd" file.
wait for it to finish, once it's done it will create a complete and official ISO files which you can use to install your next Windows insider build without any problems.
