looks like a bug in ocaml/setup-ocaml:

  D:\a\_actions\ocaml\setup-ocaml\v2\dist\index.cjs:19591
          if (!arg.includes(" ") && !arg.includes("	") && !arg.includes('"')) {
                   ^
  
  TypeError: arg.includes is not a function

Could you open an issue upstream?

Yes, you mean to setup-ocaml, although I have no idea what is the cause of the problem here. I'll open an issue there with a link to here.
