AI Functions error for text analytics

Hi jemmaa ,
It typically points to an authorization issue with the AI Functions connector in Power BI Desktop. Since you've already confirmed that your Power BI Pro license is active, you've reinstalled Power BI, and have cleared and re-entered credentials, the next likely cause is that the AI workload might no longer be enabled in your tenant. 

Even though you're working in Power BI Desktop and not yet connected to a workspace, AI features like text analytics still depend on tenant-level settings. To move forward, double-check with your Power BI administrator to ensure the AI workload is enabled in your tenant or Premium capacity settings.

Also, revisit Transform Data > Data Source Settings in Desktop, clear any cached credentials for "AIFunctions", and sign in again. If you're using a Premium workspace, ensure the AI workload is turned on in the Capacity settings in the Power BI Admin Portal.
