Adding "Run EQS" into selector causes UE to crash

When I try to add “Run EQS” into selector in behaviour tree, engine crashes. Was trying to migrate AI content from Lyra into my own game.

The reason was “Base Class” set to “None” in blackboard. Now when I changed it into my own character class, problem disappeared.
