To download newer versions of java just search up something along the lines of "java 21 download" . Since your playing on a laptop and can't access your Microsoft account, I recommend using a different launcher that supports ely.by accounts. The server will accept cracked and official accounts. Ely.by accounts offers skins instead of the normal default Steve skin. I think a good one is PineconeMC. Or again you can just set up a offline account on a different launcher that does not need a Microsoft account. My discord account is in the document I've provided if you want to talk on there.

Search Google for "Java 17 download Windows".
Download the Windows installer and run it.
Once it is installed, restart your laptop and try launching the game again.
if it still crashes after installing Java 17, I'll need to see the actual error log. Go to your .minecraft folder, open the crash-reports folder, and send me the newest text file on Discord
