Stuck on reboot.

Hey, so I’m updating my 2015 macbook pro to sequoia and it was going smoothly, when i rebooted to download the update on my macbook and chose install sequoia without erasing any old data it started the installation and it rebooted on it’s own to this screen, it did that a few times so far but I didn’t click anything because i am following a youtube tutorial that said it happened in the tutorial 4 times before it booted to normal. Is that a problem? Should i do anything? Or should i just let it do its thing through the night? Please help.
