Write a debugging guide in a {{tone}} tone for {{target_audience}} about an async/await issue in R with {{severity}} severity in a {{environment}} environment. The guide must follow a systematic debugging methodology: isolate, gather evidence, root cause analysis, implement fix, prevent recurrence. Output three sections: Bug Report Template, Diagnostic Process (5 steps with actions, outcomes, pitfalls), and Common async/await Pitfalls in R (top 10 mistakes with pattern, cause, correct approach, detection method). Maximum 600 words. Use plain language suitable for {{target_audience}}. Every recommendation must be specific to async/await in R. Skip any section if information is unknown.
