FearLess Cheat Engine

Good evening, I would like to know if it is possible to have logs on cheat engine?

Because I would like to know what is wrong with my modification because I have a crash every time.

If you're causing the game to crash you'd likely need to go through the game's log files, if it has any. You can set up a log with lua but it will only log what you tell it to, but this can still tell you some things. But CE doesn't really have a crash log.

You'd likely be better off just enabling one script at a time to find out which one is causing the crash, then set a breakpoint just before the injection then stepping through the code to find where it's crashing.
