Hey, @ttohaver!
Do you think you could give a full shot of the entire window? I haven’t seen this before, and I uninstalled/reinstalled the launcher to see if it was new to today- it is not, at least not for Windows 10 and there is nothing in today’s patch notes about it. What it looks like is a version of the launcher that exclusively has access to the Epic Games Store.
Could you get us a shot of the whole window? I may be able to look a little deeper into this, I haven’t seen this before, I can’t even find this on a reverse Google image search but that doesn’t necessarily mean it isn’t official. Get that to us and I’m sure I can help you get it figured out!
