Happened to me also, then had to quit & restart the game & also 2nd time didn't choose "hug her", instead chose "kiss her" which could be the bug.
The game freezes right after talking to Mom in the house
glad i didn't was the only who got stuck at that.
The thing is that you should talk to her in her initial position (when she's in front of the table with the phone, the exact position when you first enter) so she can go down 2 times and disappear. If you talk to her in another location, it'll mess up.
I didn't try talking to her in another place where she could go down enough to the event flow as intended an then don't get stuck.
If the dev read this message, talking in basic RPGM languaje, carmen should be fixed in the spot, not make her wander around.
or fix the event so it doesn't stuck if she can't complete the designed movement route.
Hope it get's fixed for the next release, i liked the game and will continue cheking every update.
if anyone get stucked on that part, do this.
Try to talk with her in her initial position, best if you talk to her side instead of below her. if not, go out and enter again, this will force her to go to her starting position.
After some events, you'll talk with Carmen (The milf with black dress), she will tell you that she got you a new phone, it's in the kitchen. Grab it and the menu will be enabled. It's intended in that way.
