Debugging Systematic Approach

Help me debug a problem I can't figure out.

Problem description: [DESCRIBE THE BUG]
What should happen: [EXPECTED BEHAVIOUR]

What actually happens: [ACTUAL BEHAVIOUR]
When it started: [AFTER WHAT CHANGE / ALWAYS / INTERMITTENT]
What I've tried: [LIST DEBUGGING ATTEMPTS]

Walk me through:
1. **Problem Definition**: Help me state the problem precisely
2. **Reproduction Steps**: Identify the minimum steps to reproduce
3. **Hypothesis Generation**: List possible causes ranked by likelihood
4. **Isolation Strategy**: How to narrow down where the bug lives
5. **Debugging Tools**: Which tools to use for this type of bug
6. **Binary Search Debug**: Using divide-and-conquer to find the issue
7. **Logging Strategy**: What to log and where to add log statements
8. **Common Causes**: Frequent causes for this type of bug
9. **Fix Verification**: How to confirm the fix actually works
10. **Prevention**: How to prevent this type of bug in future
