I have installed the latest version and if I launch as part of the installation, everything functions perfectly. Once I close it and re-open, thereafter it no longer has the 3D portion of the display - so no models are showing. Looking at the logs shows many lines like these:

This is on a Windows 10 Pro with a NVIDIA 750. All works great if launched as part of the install but fails after subsequent launches. I've tried compatibility settings based on similar (but not identical) situations from the forums with no luck.
Fresh install of 4.1 - all great at first launch, OpenGL issues thereafter
