In Trails of the Cold Steel I, whenever I enter the gymnasium I run into this bug (see attached image) where evereything except doors and characters is hidden and the moment I go through the exit door the game crashes.
My specs:
- i7-8750H @2.20GHz
- GeForce GTX 1060
- Both Video Card and OS are updated

Any way to fix this problem? I tried different graphic options but with no results.
Thank you for your help in advance

At the end I discovered it was luckily because of some data corrupted: once the data has been repaired the bug didn't occurred again.
