If I remember correctly, it is with her wife that you get the code, in a kind of quest or puzzle.
Although I honestly don't remember well, I haven't played for a while and I only did it like twice.
The game was crashing and in my case it was because of the mods, I had many outdated ones.
You're asking if it works without mods, why don't you try it for yourself? After testing whether or not it's the mods, all you have to do is delete them all and install them again if you want. That's what I did, and I'm playing the update just fine without any issues, the delay might be due to some objects with "jiggle physics". (At least with me)
Good luck.
Now I only remember two.
one of them is that working at the McC. Bar takes 2 energy.
The other is that when wearing the last outfit, on a nun I think, it does not give money or consume energy, it only lowers the beauty, and it counts as having already been worked on.
In a while I can play again and look for the ones I missed again, and I can try to add screenshots if it helps more.
There is another one similar to the one in the photo, where when entering with the mechanic no option appears, and to exit you have to return to the previous text.
