Get blackboard value as object returns "Variable is not in scope"

Hey folks,

i think i found a weird bug: I try to get a variable from my blackboard but it suddenly only shows “out of scope” when debugging. I found an older post with the bug ticket but it should be resolved in UE 4.26.

Why does this bug reappears again? Is there an error on my side or does the bug still exists for everyone?

Best regards
