❗
Unfortunately i did a stupid thing, VS code python linter linted the whole code ... hope this is not a problem if so will revert and only add the current changes, please let me know.

Please do try to revert the VS style changes. I suspect that this is mainly just line endings, so i'm surprised that git's autocrlf feature didn't fix this automatically.

You should be able to use dos2unix (or its equivalent under windows) to fix this without restarting from scratch.
