Make sure you have the current version of the mod from itch.io (not GitHub) installed. Use the steps: un-apply Aric's mod, delete the mod folder, move the new mod folder, and apply Aric's mod.
Otherwise install the Debug mod(https://itch.io/t/1137280/debugmod-v1) and post the error message you get. The Debug mod will stop the crashing but that does not mean that your problem is gone, rather the game accepts corrupted states in order to keep going no matter what.
