"Could not start 'hl' process, executable was not found in PATH. Restart VSCode or computer."

I was following this Heaps.io guide (Link to Guide: https://heaps.io/documentation/hello-hashlink.html) to learn about how to make my own game like "Dead Cells" but immediately encountered this issue:


In the Compile.hxml, I also tried using "-lib hldx" instead of "-lib hlsdl" as well
I tried searching for solutions but to no use, I also can't follow other guide online if I can't get past this unfortunately.
I really am following the guide to the tee and I do not know whats wrong.

NOTE: Besides Haxe & Heaps.io, I also downloaded the additional files using [haxelib install hlopenal
haxelib install hlsdl
haxelib install hldx]
