SpeedScopeExportError.txt

An unhanded exception occured.

At this point you can opt to continue, however it is possible that the aborted computation will cause additional failures.   Because PerfView generally only opens files for reading, there is no danger of corrupting  files, so it generally does not hurt to try.   However be on guard for unusual/incorrect behavior going forward.

You can of course exit and restart PerfView to be completely safe.

The fact that this exception went unhanded is a programmer error.   It should be reported so it can be fixed.  Please set along the following stack trace information which will be useful in diagnosing the problem.
