Need help reinstalling Big Sur on MacBook Pro

I'm trying to reinstall Big Sur on a MacBook Pro (A1502) since a friend of mine wants to give it away to his sister; I already erased the hard drive (no need for back ups), then selected "reinstall MacOS Big Sur".

After what I assume is the system downloading the OS, it restarts and a message tells me to wait for about 25 minutes. After that's done I get a message: "an error occured preparing the software update".

I've tried checking the date since some guides suggest a wrong date might be causing this. Also I don't understand why it says it is an update, I just want to reinstall the OS that was working before we erased the hard drive.

Currently I feel like the Mac Pro is as good as bricked, since I don't know what to do. Any help would be appreciated, thanks.
