System Information
Operating system: win10
Graphics card: Intel uhd graphics 620

Blender Version
Broken: ( 2.83.0 ) and 2.83.1 downloaded July 6
Worked: 2.83 downloaded a month or two ago

Short description of error
The renders are( almost always) correct the first time I press f12, when rendering again the object, the background or both are purple. This happens also just after opening blender and rendering the default cube.

Exact steps for others to reproduce the error
I open blender based on the default startup, then either

a) I click on the material icon, there is "Material" displayed with the little grey shpere before it. So far ok. As soon as I hover over the base color field or click on it, the small sphere in front of "Material" turns purple. Same if I open the shading tab and try to change the color there. Or

b) I just open blender and render the default cube. It renders ok, but the small sphere for the default material turns purple and subsequent renders will be purple. Sometimes just the cube sometimes the background too.

c) if I open blender and just try to change the world bg color, it doesn´t change in the render: either a) it stays grey or b) it renders purple, together with the default cube which I haven´t even touched.

I had already reported this problem (#77494) and after running the blender debug tool, it seemed that the rendering error was caused by an outdated graphics driver. So I talked to the Dell customer service. They finally installed the new Intel Driver, but the problem persists.

I send you the new debug files after the install of the newest intel driver. It might be also relevant that the debug tool starts as planned, however Blender doesn´t close by itself. I waited for some hours and then closed Blender manually.
