Suddenly getting error "We Couldn't retrieve the data model for this report. Please try again later"

Hi, Anonymous 

Based on the error information you provided, an error occurs when Power BI desktop connects to your data source and fetches data, Microsoft.PowerBI.ReportingServicesHost.ModelMetadataProvider occurs.
Power BI can't access your data because it can't access the data source. This issue can occur if the data source has been deleted, renamed, or moved, if the source is offline, or if the permissions have changed.
You can check your problem by following the following lines:
Create a new report in Power BI Desktop, and use the data source credentials that you used to access and load the data to determine if there is a problem with the data source credentials of the source table.
If you don't have issues with the data source credentials for the source report, try reducing the amount of data in the source report to see if that resolves the current issue.
In addition, you can troubleshoot software issues from cleaning up the Power BI desktop cache and reinstalling or updating your Power BI desktop.
