Failed to get sources of ocaml-base-compiler

[GalihPRep]

I'm using opam in Windows 11. I tried to install OCaml, but failed apparently because the downloaded file for ocaml-base-compiler.5.1.1 is not found. Here's what happened in my command prompt.

PS C:\Users\galih> opam install ocaml
The following actions will be performed:
=== install 5 packages
  ∗ base-domains        base
  ∗ base-nnp            base
  ∗ ocaml               5.1.1
  ∗ ocaml-base-compiler 5.1.1 [required by ocaml]
  ∗ ocaml-config        3     [required by ocaml]

Proceed with ∗ 5 installations? [y/n] y

However, I opened the link https://github.com/ocaml/ocaml/archive/5.1.1.tar.gz and the file named ocaml-5.1.1.tar got downloaded. I don't know what's wrong with the downloaded file and why Opam failed get the sources of the needed installation.

I think this is for the ocaml/opam repository, ping @kit-ty-kate

Which version of Windows 11 is it? (either ver from a command prompt - e.g. Microsoft Windows [Version 10.0.22631.4169] on mine or from "About your PC" - e.g. Version 23H", OS build 22631.4169 on mine)

Is there any possibility your virus scanner has quarantined it?

The ver said Microsoft Windows [Version 10.0.22631.4317] but in System › About it's Windows 11.
