To reproduce:
1. Create a minimal diagram on diagrams.net. (I created a box with the text "TEST" inside)
2. Export as SVG (using defaults)
3. Include SVG file as image in quarto pptx presentation and render to pptx
4. Open in PowerPoint (Microsoft 365 version 2202)
5. Get blank image with this notice:

I do not have access to Trust Center settings as per this Stack Overflow answer: https://stackoverflow.com/a/22183081

Dropping the file in to a PowerPoint file directly (i.e. bypassing quarto) works fine.
