Internet does not seem like the problem? Then you should see if Apple are having issues with their servers. Head to the Apple System Status Page and see if their servers are online.
Free up Disk Space
macOS Big Sur is a relatively large update, with over 12GB in size. This is why you must make sure to have enough hard drive space before you proceed with the update.

Update Stuck at the End
Some users report that the update suddenly freezes at the end of the process – 12.18GB out of 12.18GB. Make sure to wait it out at least 15-20 minutes and see if it gets resolved. If waiting does not fix it, then you should restart your Internet connection. Either unplug and plug the cable or turn your WiFi off and on.
