Hi,
I'm having an issue with my viewport when I put it into rendered viewport shading, this happens:
I've tried a factory reset but still same issue.

any idea's how I can sort this out?
Also can someone explain how this happens and why?
Hello! Looks like you have no lights in your scene. If there is a light it is not powerful enough and/or not pointing the correct direction (direction depends on the type of light).
If there is a light select it in the outliner and play with the power settings. Let us know if this helps!
coyohti hey! thanks it seems after restarting my system and blender a couple of times, it fixed the issue itself, but just found it weird how it happened when I've been using blender fine today.
yeah 5.0, first time it's happened also i was panicking at first whilst trying to troubleshoot.
It could be a tech issue, but also user error. But always first things to do are resetting your PC and doing all the updates available on graphics cards and stuff. Also having an extra Blender version or two to test opening the file on another version which may not have the bug. That is always super helpful, because if it opens correctly, then you know for sure it's not you and it's the Blender you were using.
