This error appears when I enter the sex menu. "newsexsystem" seems relevant to the problem.

Got it. So it looks like the additional file that fixes the strap on feature (missing a code snippet in vanilla) wasn’t applied. Did you copy/paste the files from inside of “Important” into the same folder with your game’s executable? If not, I’d do that now. If you already have, navigate down to the files>scripts>actions and copy/paste the strap on code back into your main game folder. That should fix it for you.
