Probably a cache thing. Win11 precaches a lot of stuff if you hover over it or have excess RAM. It's not as smart as SuperFetch and ReadyBoost (with an HDD) was but it's still doing similar things.
How big is the calculator app on Windows 11 that you need to cache it in RAM? On macOS, the calculator app is 6 MB. And that's containing both x64 and ARM code. How long does it take a modern SSD (6 GB/s?) to read that?
It seems that some Windows computers are generally laggy with no good reason. I could recommend installing Old Calculator.

It was a little difficult setting it up so that the calculator key on the keyboard pulls it up but aside from that it works well.

If it's the same as on Win10 it's a UWP App that needs a ton of dependencies like .net, WinUI2/XAML.
The appx is: Approximate size 21.8 MB according to https://apps.microsoft.com/detail/9wzdncrfhvn5
Win7 calc.exe had 758KB for i686 and 897KB for amd64.
You shouldn't need to cache a calculator app to make it load quickly - it opened instantly on a machine running Windows 3.0 with 2MB RAM.
Instant for me but I have a beefy CPU Ryzen 9800X3D and some crazy nvme.
And most important: no corporate spyware disguised as anti-virus, in this machine.
