Mod not loading, when the game is loading it crashes

I can't reproduce that issue.
It's most likely caused by a conflicting mod — send me more details (mods list, logs, steps to reproduce) and I'll try to help find a fix.

how can i provide those things? I am new to factorio modding, could you explain how to send those things?

Let's begin with the error message you see when the game crashes, as it might already contain some helpful information.

Log files can be found in one of the following directories, depending on your operating system.
🪟 Windows:
%APPDATA%\Factorio\factorio-current.log
🍏 macOS:
~/Library/Application Support/factorio/factorio-current.log
