I ran into a similar issue recently when switching from a local file structure to using a directory managed by another service — my code worked perfectly in one context then suddenlly started failing to load files that definitely existed.
In your case, it might be worth checking:
1 **File permissions or locks** sometimes files get locked by the OS or an external process and silently fail to load
2 **Relative vs absolute paths** are you sure the curren t working directory is what you expect when the code runs? `System.out.println(new File(".").getAbsolutePath());` can help with that
3 **Encoding or filename mismatches** especially on Windows vs Linux, weird characters or hidden extensions (like `.txt.txt`) can trip you up
If you can share the exact error (stack trace or message) I might be able to dig a little deeper but my hunch is that it's either a path or permission issue
Been burned by both before 🙃
