Material Properties-Material Preview doesnt show anything ( totally black) I start to use blender for a month so i am a beginner. If its a bad question i'm sorry but i couldnt figure out the trouble.
I'm using 2.83a
In Tabs&amp;Panes - Material Properties -the material preview doesnt show any material , its totaly black for everything.
However in rendering everything is working normally.

If someone has any idea how to fix it i will be very happy.

Thanks a lot.
it might be your graphics driver, I recently updated mine and had the same problem but when I went back to a previous version it's fixed
