Power BI Desktop Webview2 Crash while Loading Data
Hi GPS-DataAnalyst , Thank you for reaching out to the Microsoft Community Forum.
This points to a breakdown in how the Power BI interface renders large models, rather than a problem with your actual system resources. Even though your machine is powerful, the problem lies in the number of queries and the UI load they generate. Power BI uses WebView2 (based on Chromium) to render visuals and dialogs. When that rendering process exceeds what the sandboxed environment or Windows GDI can handle, it crashes. This isn’t about total RAM or CPU but about rendering limits and UI resource exhaustion.
Go to Power BI's options and disable hardware acceleration. This forces the app to use software rendering, which reduces strain on WebView2 and often stops these crashes. Next, update the WebView2 runtime using the official Evergreen installer from Microsoft’s Edge developer site, this replaces potentially buggy or outdated versions that ship with Power BI. Most importantly, consider breaking your PBIX file into smaller, domain-focused files. With this many queries, the model is simply too heavy for Power BI Desktop to handle reliably in one go. You can offload logic to dataflows or use shared datasets to keep everything manageable and still connected.
You don’t need to reinstall Power BI again. The crash isn’t unique to your setup, it’s a limitation of how Power BI Desktop handles large models with complex dependencies. The only reliable way forward is to reduce the rendering and query load inside the file.
If this helped solve the issue, please consider marking it “Accept as Solution” so others with similar queries may find it more easily. If not, please share the details, always happy to help.
Thank you.
