We are experiencing the same issue. Report doesn't use Python script but uses Smart Narrative. This started once the Smart Narrative issue was fixed.
It might be worth removing the Smart Narrative visuals and publish back to your workspace. We are in the process of trying that.
It is now failing for all our reports - even the ones without Smart Narratives 😕
