I can not enter my save

To clarify, are you not able to reach the main menu of the game, or is the crash happening after you choose to load the save?

Can you attach the output_log.txt?

Thanks!

Changed Status to Fixed

Assuming it's the issue with loading the save, I've fixed this for the next hotfix on the testing branch. Because the crash is occurring due to multiple pipes on the same cell, the game will now delete one of them when it loads.  You'll need to reconnect that pipe to its neighbors.

Thanks for the report!
