@cesarleeds when does it happen? After the phone restart for the start of the update? Or at the phone update app? If it is the later just download the zip file from the website and install it manually.
It just happened when trying to install the update from the Docs /Files app.
Also the Update app was not even able to download the update.
So I put the zip on sdcard/, restart, enter recovery mode and from there it worked.
And I gotta say this update fixed some weird battery issues from the previous one (charging was painfully slow, it didn’t even charge completely after 7 hours)
So far so good.
