Unreal Engine 4.21 Released!

Today, after this update the launcher looks like this

And it asked me to install Unreal Tournament at startup…
All controls now VERY small. Menu exists, but it’s 20 pixels at left corner.
I can’t start editor.
I’ve deleted all config folders, but it’s still the same.
Even after reinstallation this problem is not gone.

What I need to do to fix that?

PS. Mac OS 10.12.6 (iMac 27")
