Hi @carlosSuazo 

Iam not 100% sure if this is a known issue with custom visuals (including the Gantt chart) after Power BI updates. But here are some options you can try to fix it:

Quick fixes to try first:

1. Remove and re-add the visual: Delete the Gantt visual from your report and add it again from AppSource or your organizational visuals

2. Import from file: Download the Gantt visual (.pbiviz file) directly and import it via "Import a visual from a file" option - this often resolves version conflicts

3. Restart Power BI Desktop: Close and restart Power BI Desktop 2-3 times (some fixes take effect after multiple restarts)

4. Update Power BI Desktop: Ensure you're running the latest version - older versions may have API compatibility issues with updated visuals

For Power BI Report Server specifically:

• Verify the visual is supported on your Report Server version - not all custom visuals work with Report Server
• Check if organizational visual settings in the admin portal are blocking it
• Report Server has stricter requirements and may need the visual to be certified/approved

If the visual works in Desktop but not in Report Server/Service, it's likely a version compatibility or admin policy issue.

Best regards!
