I’m normally quite understanding, but come on, how can you expect to get meaningful help without providing at least very basic information on what operating system you’re using, the version of Syncthing, the environment (e.g. Docker, WSL, etc.)?

Also, if you search the forum for “incorrect function”, you can find multiple topics where a similar error message was present, and it seems that it’s usually caused either by misconfiguration of the OS/environment, or simply the environment not supporting file watching (e.g. when running Syncthing inside WSL).
