Psycho-Sleuth: Chapter 2 Softlock (Workarounds)
Short answer
Suggested fix (unconfirmed): Update your game to the latest version. Restart the game if necessary.
The problem
When asking where the killer was hiding the whole time, picking the wrong choice causes an empty textbox to appear, and the game softlocks.
