This PR logs the error `CreateProcessA` returns when failing on windows.
This can help with figuring out why the launcher `Failed to Launch the
game!`

 The launcher is the way we communitcate to outside the game, it does a few automated actions such as but not limited to: downloading the mod, launching the game, and create a connection to a server.

-
-## Running out of RAM while building
-
-Should you run out of RAM while building, you can ommit the `--parallel` intruction, it will then use less RAM due to building only on one CPU thread.
-
-You can also specify a number of threads to use, for example `--parallel 4` will use four CPU threads, but due to the small project size, you may be faster just omitting `--parallel` instead of trying to find the highest possible multithread number
