I am having two issues that are basically making my whole data estate and data visualization processes within PowerBI completely inoperable. #1 - Anytime I try to open a PBIX I am met with the following error: "We weren't able to restore the saved database to the model". ExecuteXmla failed with result at Microsoft.Mashup.Host.Document.ExceptionExtensions.GetCurrentInvocationStackTrace() at Microsoft.Mashup.Client.UI.Shared.FeedbackErrorInfo.GetFeedbackValuesFromException(Exception e, String prefix) at Microsoft.Mashup.Client.UI.Shared.FeedbackErrorInfo.GetFeedbackValuesFromInnerExceptions(Exception e, Int32 depth) at Microsoft.Mashup.Client.UI.Shared.FeedbackErrorInfo.CreateAdditionalErrorInfo(Exception e) at Microsoft.Mashup.Client.UI.Shared.FeedbackErrorInfo..ctor(String message, Exception exception, Nullable`1 stackTraceInfo, String messageDetail) at Microsoft.PowerBI.Client.Windows.Telemetry.PowerBIUserFeedbackServices.ReportException(IWindowHandle activeWindow, IUIHost uiHost, FeedbackPackageInfo feedbackPackageInfo, Exception e, Boolean useGDICapture) at Microsoft.Mashup.Client.UI.Shared.UnexpectedExceptionHandler.<>c__DisplayClass14_0.<HandleException>b__0() at Microsoft.Mashup.Client.UI.Shared.UnexpectedExceptionHandler.HandleException(Exception e) at Microsoft.PowerBI.Client.PowerBIUnexpectedExceptionHandler.HandleException(Exception e) at Microsoft.Mashup.Host.Document.ExceptionHandlerExtensions.HandleExceptions(IExceptionHandler exceptionHandler, Action action) at Microsoft.PowerBI.Client.Program.Main(String[] args) PFE_SYSTEM,PFE_METADATA_LOAD_FAILED The following system error occurred: Class not registered An error occurred when loading the 'feb67b54-6dbc-405f-ad38-0cac728e81b7', from the file, '\\?\C:\Users\khari\Microsoft\Power BI Desktop Store App\AnalysisServicesWorkspaces\AnalysisServicesWorkspace_c4c68a2e-7fa8-4134-9b2a-3b7763180ac2\Data\feb67b54-6dbc-405f-ad38-0cac728e81b7.0.db.xml'. at Microsoft.Mashup.Host.Document.ExceptionExtensions.GetCurrentInvocationStackTrace() at Microsoft.Mashup.Client.UI.Shared.FeedbackErrorInfo.GetFeedbackValuesFromException(Exception e, String prefix) at Microsoft.Mashup.Client.UI.Shared.FeedbackErrorInfo.GetFeedbackValuesFromInnerExceptions(Exception e, Int32 depth) at Microsoft.Mashup.Client.UI.Shared.FeedbackErrorInfo.GetFeedbackValuesFromInnerExceptions(Exception e, Int32 depth) at Microsoft.Mashup.Client.UI.Shared.FeedbackErrorInfo.CreateAdditionalErrorInfo(Exception e) at Microsoft.Mashup.Client.UI.Shared.FeedbackErrorInfo..ctor(String message, Exception exception, Nullable`1 stackTraceInfo, String messageDetail) at Microsoft.PowerBI.Client.Windows.Telemetry.PowerBIUserFeedbackServices.ReportException(IWindowHandle activeWindow, IUIHost uiHost, FeedbackPackageInfo feedbackPackageInfo, Exception e, Boolean useGDICapture) at Microsoft.Mashup.Client.UI.Shared.UnexpectedExceptionHandler.<>c__DisplayClass14_0.<HandleException>b__0() at Microsoft.Mashup.Client.UI.Shared.UnexpectedExceptionHandler.HandleException(Exception e) at Microsoft.PowerBI.Client.PowerBIUnexpectedExceptionHandler.HandleException(Exception e) at Microsoft.Mashup.Host.Document.ExceptionHandlerExtensions.HandleExceptions(IExceptionHandler exceptionHandler, Action action) at Microsoft.PowerBI.Client.Program.Main(String[] args) # 2 -Anytime I try to create a new PBIX and add data sources, I run into the following error: Failed to save modifications to the server.

I've updated my laptop, reinstalled Power BI Desktop, reinstalled all the MS DB Drivers (OLE, ODB) and nothing works.
