Hello , i was playing the game , almost finishing the event of Kate where at the end lvls up the relationship with her at 8 but right after that i got this error , that keeps happening whaterver i go or do in the hotel and had to stop because it started to be unplayable. Is there any solution to this?
Top right corner of your screenshot shows you are playing a beta version. Beta versions are buggy, do not work properly.
Where did you even get one of those beta versions?
You should use a released version, those are at least supposed to work. Find the latest released version a bit up on this page, under the heading “Download”.
You may need to start game from the beginning, I remember there was talk the saves made with beta version do not work on the released version of game (since the beta versions are buggy …).
Do not download anything from third party copycat sites, those may contain malware. Also, do not pay for downloads from those pirate sites, since downloading this game from the official site is no charge (although you can pay the amount you want if supporting game developers is your thing).
