When Opening ANY Blueprint from any project. The Details are not showing.
What I tried to fix:
Getting the same issue here but it seems to be random - I get the labels in the blueprint editor, but I don’t get them in the scene editor. Unsure of what could be causing this discrepancy.
Yeah I have no idea and i cannot work on my project now… I have tried every little thing to try and get the labels to reappear, but they are just gone. Fresh Install of engine? Still gone. New Proejct? Still gone.
Can corroborate that a new project/fresh install doesn’t fix it for me either 
Even updated my graphics card’s driver and that didn’t work.
Made a video of a brand-new project.
Made my own fix sense I got zero support. IF ANYONE EVER COMES ACROSS THIS
do this;
UNINSTALL Unreal Engine.
Go to C:\Users\USERNAME\AppData\Local\UnrealEngine\
DELETE the 5.0, Common and Editor folder.
Go to C:\Users\USERNAME\AppData\Roaming
DELETE the Unreal Engine Folder.
Reinstall.
Issue fixed.
I only deleted the “Editor” folder in there and this did it for me. Didn’t even have to uninstall UE or delete the other folders, thanks a ton!
It’s that simple of a fix, then there it is! awesome 
… 5 hours trying to figure this out and it was such common sense stuff lol
In the main editor window:
Window → Load layout → Default editor layout
did you even read the post? or even watch the video? Im sorry but next time read and watch a video before posting. You can’t just assume something. and post a solution. This is not how things work. The post clearly states: " * Reset the Editor to Default Status; By Changing the Layout to Default."
Sorry, but it doesn’t make sense. You say the details panel is missing, but in your ( tiny ) picture, the panel is obviously there
Wait, ok, I see what you mean, some of the details are missing. Hold on…
Solved it - gimme a minute…
