it looks as if B79 does not let workspace load strategy parameters correctly, does not load data and does not run automatically (despite "Auto-Run...." clicked on)

What's the easiest way to roll back this update?

Thank you

It looks like the latest fix for this known issue is incomplete. Your stack trace suggests a MetaStrategy being loaded (in the workspace) and failing. We'll check.
