SP freezes when loading a new mesh

[Froyok]

Alright, I'm not sure exactly why you are freezing then. You will have to try a few things :

• Can you downgrade your GPU Drivers to version 430.86 ? (I noted you already did that, but didn't mention any version)
• Can you reset your preferences (remove them from the registry) ? See: https://docs.substance3d.com/spdoc/application-preferences-location-147095594.html
• Can you check this page to see if your Windows installation is working as expected ? See: https://docs.substance3d.com/spdoc/crash-or-freeze-during-startup-182266673.html
