Hi! We're so sorry such a bug occured in your playthrough.
In order to fix this we'd need to replicate it on our end, and having your save file right before the crash happens will help a ton!
On Windows saves are stored in:
C:\Users\ [username] \AppData\Roaming\RenPy\ACADEMY34-v0.2.3
You can upload it on Mega or Limewire, or any other cloud site and we will take a look!
