Alright I figured it out, turns out the problem was with the itch windows app, I think it has a hard time with rar files. The error reads: "dmc_unrar_extract_file_with_callback: error 44: RAR 5.0 block checksum doesn't match" whatever that means. I got it to work no problem on the web version of itch. Cool game, simple graphics but I'd suggest making the cursor/guitar pick thing a bit smaller to make it a bit more challenging as right now you can put yourself in between the two lines and hit all the notes
