Just have checked this on 4.23 - everything is ok. Can you check it on some old version? Also, is this error thrown when you try to compile? Try to save user struct and then recompile BP.
This error occurs when I compile either the widget (100% of the time on first compile, then it works until I edit the structure BP), or when I compile other blueprints (I haven’t seen any noticeable consistency when other blueprints compile throws the errors).
I just opened up the editor fresh 4.26 p7, compiled the widget and it throws the error.
