MacBook Air stuck on 'checking for updates' during software update

I want to update my software to the newest version in order to improve the speed of my MacBook. But any time I go to update my software on my MacBook Air (2020) it just sits and load and give me no additional info, or an opportunity to update. It just sits on the loading screen saying checking for updates! My Macbook runs on BigSur.

I've already logged out and restarted my mac several times, but with no luck!

Any suggestions?
