Can't Update to Big Sur 11.5.1

Everytime I try to update to Big Sur 11.5.1 it does the download and then freezes with exactly 15 minutes remaining and when clicking on the x it says the failed to download check the Internet connection but my Internet connection is just fine (high speed, hardwired Ethernet).


I've tried 5 times to update so far with the exact same problem each time.


I'm on a new 27 inch iMac that came with Big Sur installed.


Thanks for any help!
