I have a desktop application written entirely in Python that is misbehaving, and I need another set of eyes on the code. The core logic is already in place, but certain functions crash unpredictably and performance has taken a hit since the last update. Your task: • Identify and isolate the root causes of the current errors. • Patch the bugs without breaking existing features. • Clean up any obvious performance bottlenecks you find along the way. • Provide a concise report outlining the fixes and any recommendations for future refactoring. The project is strictly about debugging—no new features required—so I expect focused, well-documented commits and clear communication as you work through each issue. If you are comfortable stepping through Python code, profiling troublesome sections, and submitting clean pull requests, I’d love your help to get this application stable again.
