Power BI Native Filled Map Visual Not displaying Country Location

Dear Team,

I have been utilizing the map visual feature for an extended period. However, approximately two hours ago, the same map visual ceased to display any country locations.

I have already ensured that the Power BI cache settings are cleared and that the country has been designated as a category for the field utilized in the map visual.

Additionally, I conducted a test with a sample Power BI report by extracting only a country name and attempting to display it in the map visual. However, the visual remained empty.

Could you please provide guidance or investigate the root cause of this issue?
