Thanks for reporting this! This was a bug in the report.query_store_regressions inline TVF — the SQL view was missing 5 columns that the Dashboard C# code expected.

The fix has already been merged and is included in the updated v2.0.0 release. Re-running the installer will update the view and resolve the error:

PerformanceMonitorInstaller.exe YOUR_SERVER sa YOUR_PASSWORD --trust-cert --encrypt=optional

The installer is idempotent, so it's safe to re-run on an existing installation.
