Looker Studio says “You don’t have access to this resource” in sharing settings, even though I’m the report owner

Hi,

I’m having an issue with one specific Looker Studio report.

The report appears under “Owned by me”, and the owner column shows my own account as the owner. However, when I open the sharing settings from the report list, the sharing dialog shows the following error:

“You don’t have access to this resource.”

Also, when I try to open the report URL, I get:

“Failed to get report. This report is not shared.”

I have already confirmed that I’m using the correct Google account. Other Looker Studio reports open normally with the same account, but this one specific report cannot be opened or shared.

This does not seem to be a data source credentials issue, because I cannot even open the report or manage the report sharing settings.

Has anyone seen this before? Could this be caused by an ownership/permission metadata issue, an authuser/account issue, or an organization-level restriction?

Any advice would be appreciated.
