I played a while on version 0.17 and now I switched back to 0.16.51 to check something bug the game won't start. The problem seem to have something to do with mods.
I've removed the folder "mods" and now the game is starting properly.
Although, all mods was disabled before I switched the version.

Edit:
This may be useful:

Thanks for the report however that's working correctly: the mod(s) aren't compatible with the older version of the game and the game can't show the "failed to load mods" messages because it fails too early in the processing of the mods.

I would still call it a bug.
If there is some problem with processing mods, there should be a message for the user that explains that.
Game closing itself right after it is started, without any kind of information, isn't something I would call correct.
