Your installation may have gone awry - I hope you have a backup just in case. But it is also possible that there’s something blocking that startup process which we can fix.
The first thing you’ll want to do is restart while holding the shift key - this is a safe mode start. Safe mode runs disk first aid as well as deleting caches and it launches with a minimal set of drivers and extensions and doesn’t launch any applications. Due to the diagnostics it will take longer than normal so don’t think it was another fail when the Finder doesn’t appear in 20 seconds. If the computer does start completely and you get to the Finder try restarting normally and see if that cleared things up.
