• stable 1.75.0
• checking the monacoworkbench/unresponsive.sample-event

(each entry is a separate event but they might all share the same cause)

Reading help 📖

• The Fn column is the function that the profiler identified as slow (see avg_TotalTime for the avg durations and dcount... for the number of affected machines)
• The Callers column is the "heaviest" call-stack into that function, each calling function is separated by the < character (kusto escape gymnastics...)

While digging into #174039 I realised that I had queried kusto wrongly - the data was pulled for stable and 1.75 insiders. For the latter we have seen and fixed this issue. When querying properly (only for 1.75.0 and 1.75.1) this doesn't show up anymore
