Sub Panel VI gives me Error 1036 at Invoke Node

[ShogunOrta]

I don't get it. This program used to work. But now I get Error 1036 at the same Invoke Node. I feel like this should be pretty straight forward, but....nope. Anyway, here's my code. Just fill in the file path to whatever VI you have of your own.

Sorry, that was Error 1026.

Are you closing the ref to the inserted VI?

Wire the error out from the "insert" node to the error in of the close reference.

Yep, you have a classic race condition.  The Close is just barely getting executed before the Insert VI, causing your Insert VI to have an invalid reference.  As was already said, use the error cluster to make sure your functions operate in the proper order (use data flow).
