Neovim TreeSitter Returning No C Complier Error

I am very new to neovim and the vim ecosystem. I am still trying to get started with my own config file, however, I am running into an issue when downloading Kickstart from https://github.com/nvim-lua/kickstart.nvim. I copied the init.lua file into my own file and ran it. It downloaded all of the correct things, however, there seems to be an issue with the treesitter plugin. When I ran :so on my init.lua file, it gave and error.

Re-sourcing your config is not supported with lazy.nvim
Error detected while processing :source (no file):
No C compiler found! "cc", "gcc", "clang", "cl", "zig" are not executable.

This is my second time trying to deal with treesetter. The first time around I downloaded GCC to try and fix the issue. Nothing worked so I decided to delete the whole thing and download kickstart to begin the config process. I need a bit of help with this issue as I am not familiar with Vim yet.

Edit: This is the :checkhealth nvim-treesitter command that gave the following.

nvim-treesitter: require("nvim-treesitter.health").check()

    c(highlights) is concatenated from the following files:

  - ERROR: c(locals): Failed to load parser: uv_dlopen: C:\Users\sadda\AppData\Local\nvim-data\lazy\nvim-treesitter\parser\c.so is not a valid Win32 application.

As you can see, gcc is available, so I am not sure why this is not working.

Based on How to install and set up Neovim on Windows:

Like the error says, you need to install cc, gcc, clang or zig.

Windows

If you have choclatey installed:

choco install zig

Otherwise, you can install Zig directly from their website: https://ziglang.org/learn/getting-started/

Ubuntu

Based on IT'S FOSS — What is Build Essential Package in Ubuntu? How to Install it?:

Install the essentials:

sudo apt update && sudo apt install build-essential

Run Neovim again and the error goes away.

Tree-sitter needs to locate correct libraries such as "libstdc++-6.dll" among others. Such dll files are included in Neovim directory. To ensure that Tree-sitter correctly locates correct version of libraries, modify your system's Path environment variable so that the path to Neovim is above other paths that might have dll files.

To do that, follow the instructions below:

  1. press WindowsKey + R
  2. Type sysdm.cpl ,3
  3. Click on Environment Variables
  4. Under User Variables, there should be a Path variable with some values in it.
  5. Double click on the Path variable
  6. You will see a list of Path variables
  7. Click on the item which has path to Neovim executable
  8. Press move up button a few times so the system can prioritize dll files in Neovim directory.
  9. Now do a :TSUpdate all inside Neovim to recompile Tree-sitter parsers.
