Power BI File Won't Open

Hi bkxn226 ,

You can refer to this thread:

https://community.powerbi.com/t5/Desktop/quot-We-weren-t-able-to-restore-the-saved-database-to-the-model/m-p/345979 

This issue is caused by a mismatch in the regional settings of your locale and your application.

There is a workaround: in Power BI Desktop, you will need to go to File > Options and settings > Options and update the Regional Settings -> Application language for your locale so that it matches your OS locale settings, or uses the Windows default display language.

Best Regards,
Liang
