Anyone’s software update bugged?

As Tahoe is a complete no-go, Sequoia 15.7.3 is the go-to for me. Issue is, every time I click ‘Update Now’ it does absolutely nothing. It’s like I’ve never even pressed it despite me clicking several times. When I go to the ‘i’ it shows me the same firmware but again when I click ‘Update Now’ nothing happens whatsoever.

I have enough storage space 1TB, restarting etc etc but nothing seems to work. Any ideas?
