HOTRELOADED Reference error after hot compile

Hi all, here is the case, I have an actor component attached with the BP (MyCharacter) call ColorSlotManager, and everytime I edit some codes in c++, after I hit compile in editor and trying to save the MyCharacter BP this error comes out, it’s like the component reference no longer working. Any idea how to fix this? right now my solution is to recompile in vs then it works.
