Trying to change path but it shows up "error has occured"

Hello! I'm trying to use S4S to create things and I'm having trouble setting the path for my Sims 4 game in settings. I've followed videos and everything else but something is wrong. When I click on the "..." to change it, it won't let me click on anything else. Instead, a window pops up and says, "An error has occured. Please report this. Thanks " I'm getting so frustrated because I don't know what else to do. Can anyone help? Thanks!

Edit: I also have Mac
