Bug Report: Invalid Perspective Definition Prevents PBIP Model from Loading in Power BI Desktop

Issue Description

When a developer renames measures that are included in a perspective within a PBIP model, Power BI Desktop fails to load the PBIP file. The error message is generic and does not specify which measures are invalid in the perspective. Since Power BI Desktop does not support perspectives, an invalid perspective definition should not prevent the PBIP model from loading.

Steps to Reproduce

1. Open Tabular Editor and define a perspective in a PBIP model, adding several measures to it.
2. Rename one or more of the measures that are included in the perspective.
3. Save the changes and attempt to open the PBIP file in Power BI Desktop.

Expected Behavior

• Power BI Desktop should still load the PBIP model, even if a perspective contains invalid references.
• If an error occurs, the message should clearly indicate which measures are invalid in the perspective.

Actual Behavior

• Power BI Desktop fails to load the PBIP file.
• The error message is generic and does not specify the problematic measures.
• The only way to resolve the issue is to manually edit the perspectives.tdml file.

Proposed Fix

• Allow PBIP models to load in Power BI Desktop despite invalid perspective definitions.
• Improve the error message to indicate which measures are causing the issue.
