Please refer WPA perf extension (PerfDataExtensions). original issue link is blow

Can you please share more data about the error and what you're see?
Jan 28 '23 00:01 brianrob
hmm, nothing other than these. the Loading dialogue quickly disappears and Diagnostic Console shows the error. I feel this is 50% probability Or maybe 100% failed at first, then second loading succeeds

I see - this is an issue with the ParallelLinuxPerfScriptStackSource:

This looks like it's a missing lock or other multi-threaded access protection mechanism. This will require a change in TraceEvent to fix.
Jan 28 '23 00:01 brianrob
Is it PerfView side or Extension side?
Jan 28 '23 00:01 ami-GS
This is an issue in TraceEvent which is the library that drives PerfView. This is the right repo for this issue.
