Good day.
When I've booted the project that I've been working on for some time now up today, after the 2018.2 update, the first time I switched to 2D view it's contents flickered for a moment and turned black. Now I functionally do not have a 2D view, just a square of lighter shade of dark grey where the textures used to be. I've tried reinstalling my graphic card drivers, rebooting, starting a new project but none of that helped.
Just in case, I should note that I am using Steam version of SP.
