New projects with default settings are all grey in viewport

Hi Everyone,

I tried to create new project with default settings and I tried this in 4.26.0, 4.25.4, 4.24.3 and my viewport is all grey. See screenshot. I Also tried to create a new level and all is black. Even when I created a directional light or pointlight. When everything is grey and I click on an object then I can’t move the object. The pointers to move the objects are not visible. I tried in different templates but the result is also the same.

Is there a setting that I’m missing? I re-installed different versions and they are all the same.

If anyone can help me out then I appreciate it a lot.

Thanks in advance.
