Why can't I update Macbook Air from Catalina 10.5.1 beta to a newer version?

My current Catalina version is 10.15.1 Beta (19B86a), but when I check to see if there's an available update, it says that my Mac is up to date. I downloaded Catalina 10.5.4 update for an upgrade but I got no luck, it gives me an error as stated on the screenshot below. I thought I need to update my beta version first before upgrading to 10.5.4, so I downloaded Catalina 10.5.1 update, but same error persists. Could anyone tell me what's going on?


MacBook Air 11″, macOS 10.15

Perhaps you could fully remove Catalina Beta versions; and start in Recovery, run repair disk.


And then see about either Mojave 10.14.6 first, &/or see IF the non-beta 10.15.4+ is supported

in your build/year version MacBook Air. ~ (Could be it's not.) +May need more RAM, if older.
