undefined error window poping up,not closing

Hi dilbagsidhu 

Based on your description, it seems you're encountering a persistent "undefined error" when attempting to create a visual in Power BI, which also prevents you from saving your file. 

Firstly, it's important to ensure that your Power BI Desktop is up to date. Outdated versions can sometimes cause unexpected behavior.

If updating does not resolve the issue, try clearing your Power BI Desktop's cache. This can sometimes resolve unexpected errors.

Additionally, it's worth checking if there's an issue with the specific measure or data model you're using. Try creating a simple visual with a different measure or dataset to see if the error persists. This can help isolate whether the problem is with the specific measure or a broader issue with Power BI Desktop.

If the problem continues, consider using the Power BI Service (app.powerbi.com) to create your visual as a workaround. You can upload your PBIX file to the Power BI Service and attempt to create the visual there.
