Looker studio report no longer accessible by any users

Hello - yesterday, one of our Looker studio dashboards became inaccessible along with all of its associated data sources.

https://lookerstudio.google.com/reporting/67c34f4d-ab49-4295-a5d7-03430262995b/

We have verified that the report is not in the trash. None of the individuals who previously had access to the report, including members of the organization the report belongs to, are able to access the report.

Combing through the forums it looks like this issue has been surfaced previously - is anyone aware of a resolution? Can anyone from the Google end provide insight?
