Confirm the download source
Use the creator's itch.io page and extract the complete archive before launching it. Do not download repacked executables from unofficial mirrors.
Try the current build
The project is actively updated. Re-download after a development-log fix rather than mixing files from different versions.
Preserve the folder
Keep the executable beside its supplied data files. Moving only the executable can leave required dialogue or Unity data behind.
If the problem continues, check the latest official comments and report the device, Windows version and exact step where the behavior changes.
