Hey everyone, I recently ran into the same problem where the Surface Viewer is not working properly. For me, it either wouldn’t load the 3D model or just froze on a blank screen. After some digging, I realized it was due to outdated graphics drivers and a recent update conflict. What worked was updating my GPU drivers and clearing the app/browser cache. Also, make sure WebGL is enabled if you’re using a browser-based viewer. Hope this helps someone else facing the same Surface Viewer not working issue — it’s super frustrating but usually fixable with a few tweaks!
