3D viewer not working on Windows 11 with AMD Vega 10 graphics

I tried toggling the check box for OpenGL (Rendering Method). Still no luck. If I enable the Graphics on Device Manager, the black thing on the 3d viewer disappears.

Huh that is really strange, never seen something like that.

Honestly I suspect there is something wrong with the graphics driver. I cannot guarantee it, but very often, strange OpenGL problems which occur only on very specific devices, are caused by faulty graphics drivers. Sometimes it helps to uninstall/reinstall the graphics driver, or switching to a different driver (e.g. uninstalling the driver from Windows and installing the driver downloaded directly from the graphics card vendor).
