Thank you for reporting this! Unfortunately, there appears to be a problem with our reporting mechanism and the important portion of the error report was omitted. We are aware of the problem and are working to fix it. Given the lack of actionable information (our fault, not yours) I'm going to close this issue.

the important portion of the error report was omitted

It should still be available in C:\Users\giote\AppData\Local\Temp\report.txt local file
