Hi! I already tried to reinstall the VS2017 Community with the checkboxes of Unreal Installer and tried to build 4.16 and 4.17, both are just crashing when I hover my mouse on some menus like the image below (PackageProject):
Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:B:\Dropbox\UnrealEngine\Engine\Source\Runtime\Core\Public\Containers/Array.h] [Line: 596]
Array index out of bounds: 0 from an array of size 0
