Debug My Python Tool

I need help repairing a Python codebase that powers a tool running on a non-standard platform (it isn’t Windows, macOS or Linux). After a recent change the program now throws runtime errors during start-up and two key routines—file parsing and CSV report generation—no longer behave as expected.

You’ll dive into the existing source, trace the faults, and introduce clean, well-commented fixes without reshaping the overall architecture. I’ll grant Git access and provide a Docker image that mirrors the target environment so you can reproduce and verify the problems locally. The task is done when the application launches error-free and the current unit tests all pass.
