Broken: version: 2.91.2, branch: master, commit date: 2021-01-19 16:15, hash: rB5be9ef417703
Worked: (newest version of Blender that worked as expected)
Short description of error
All of my projects have suddenly lost all materials and textures. In viewport materials preview, all objects are grey, and in viewport render preview, a black shape appears when moving the camera around objects on top of everything being greyed out. Reapplying Materials, restarting, or trying to add new materials or textures does nothing. The creation of a new project and attempt at material assignment does nothing as well.
Exact steps for others to reproduce the error
Error happens every time on start up for any project. complete reinstall of latest version of blender yields same results for new and existing projects.
