I am new to blender 2.91 and only started working with it recently. I ran into a problem.
Each model that I have downloaded and imported seem to go invisible whenever I go into “Material Preview” or “Wideframe”. The model turns invisible with only its bones and outlines visible.
My computer is strong. However, it has an old part to it. An HDD. My guess is, that it is the cause of the issue. It runs on a free Windows 10 as well. I am wiping it and getting it replaced soon with a 500gb SSD. However, my laptop that can barley run Blender 2.91 without burning down loads these textures, while my “NASA” PC does not.
Another one of my guesses is that something that was installed on my PC before blender is messing with it.
P.S This happens to any model no matter of developer or file.
