Synoptic Panel crashes Power BI with "There's a problem with WebView2"

I'm using the Synoptic Panel by OKVIZ visual in Power BI Desktop to visualize a Boeing 757-200 aircraft diagram across three orthographic views: top, front, and side, each displayed in its own Synoptic Panel visual.

Environment

Power BI Desktop: 2.154.1260 (May 2026)

Synoptic Panel: 2.5.7

OS: Windows 11 Enterprise

Hardware: i9-14900X · RTX 3500 · 64GB RAM · 2TB SSD

What's happening

My workflow is to configure one Synoptic Panel visual with all formatting and changes first, then copy-paste it twice to create the other two views, swapping in the appropriate SVG for each. The page ultimately has 6 Synoptic Panel visuals in total (3 aircraft views plus others).

The crash follows a very specific and reproducible sequence:

  1. Configure one Synoptic Panel visual

  2. Copy-paste it twice for the remaining two views

  3. Attempting to save crashes Power BI Desktop immediately with "There's a problem with WebView2"

Question

Is copy-pasting Synoptic Panel visuals a known trigger for WebView2 instability? Is the crash being caused by something else?
