Every time I try to destroy something (left click) it opens the config for the game. I can't change it and it makes the game unplayable. :(

No, it is a glitch. It is set to H+c like the default. Restarting the instance and changing the hot key and changing it back don’t do anything either.

Did you change the hotkey to open the config menu to LMB? You can change it through Mod Menu without needing to be in-game

"config for the game"? What menu opens exactly? If you didn't change the config menu hotkey openConfigGui, then did you maybe change the Shape Editor hotkey shapeEditor?

Yes the shape editor hotkey is right bracket and it works. Also when I removed the mod and reinstalled it and changed the setting back to what they were it fixed it
