Since the issue occurs in multiple browsers, it is unlikely to be caused by your browser. Start by confirming whether other users are experiencing the same issue and check the Power BI service health. If the problem is limited to your account, review your permissions and try accessing the report directly from the workspace. If multiple users are affected, the issue is likely with the Power BI app, dataset, or Microsoft service, and it should be escalated to your Power BI administrator for further investigation.
