itch.io

whenever I try and launch, it gives an error message saying:

Unable to parse Build/Piper's Playground framework.js.br!

any idea how to fix this?

I've tried reinstalling and fully uninstalling (the two separate options on the itch.io app)

edit: tried opening in browser and it seems to work just fine?

I downloaded the plus version but I can't figure out how to open it, I just have an .html and a .js in the .zip (aside from the other folders)

I'll admit here that I'm not the best with computers beyond digging through files, and have no clue how to run this plus version
