You can just ignore the quest objective and go straight to a sex shop on jig jig street, it is located near the joytoy icon, food icon and a fixer icon on the map. In the shop, you can ask the cashier about a special BD and your quest objective will change
EDIT: This happened to me during the disasterpiece questline, hope we are talking about the same issue. If not, then sorry i wasted your time, but you can still try to apply the same logic, find the quest playthrough on youtube and try to go to the next mission objective without talking to wakako. Hope this helps
This worked for me! Thanks for posting a workaround dude!
