Power BI DesktopPower BI Desktop launch error

Hi Dumitru79,

Thank you for the follow up.

Based on my understanding, since the error recurs even after reinstalling WebView2 and Power BI Desktop, the problem appears to be environment related. It is likely associated with virtual server configurations or scheduled processes that affect the WebView2 runtime or the Analysis Services workspace used by Power BI Desktop. Power BI Desktop depends on the Microsoft Edge WebView2 Runtime and a local Analysis Services instance (MSOLAP$AnalysisServicesWorkspace). On virtual servers, automated processes such as snapshots, system re-provisioning, or security policies can modify or remove WebView2 or corrupt the Analysis Services workspace files after a few days, causing visuals to fail to render.

Please follow the steps below, which may help resolve the issue:

1. Confirm with your VM administrator that the server is not being reverted to an earlier snapshot or image after a few days. Ensure that the WebView2 and Power BI Desktop installations persist across reboots.
2. Open Task Scheduler and disable or monitor the MicrosoftEdgeUpdateTaskMachine and any security or cleanup tasks that may periodically modify system files. Ensure that antivirus or endpoint protection software is not quarantining Power BI or WebView2 components.
3. Add a user environment variable named:
   WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS = --disable-features=RendererCodeIntegrity
   Restart Power BI Desktop afterwards.
