i tried updating some mods because new versions were available, and after restarting the game fails to load even after attempting to reinstall them. i included a screenshot of the mods that were updated before this happens with error logs

Try downgrading aon helper, seems like there's some sort of failed integration with Reverse Helper

#

(or alternatively, disable one of the two mods, I guess)

downgraded a version and now the game is up and running
