Cannot see my custom c++ character in blueprint

I created C++ character class
i’m trying to create blueprint that derive from this class

I cannot see my C++ class in the pick up parent class menu anymore

i was able to do this in 4.17, how to do it in 4.19?
Update
creating new project it works.

but im unable to copy my existing code in the new project. i have to redo everything

I created Class A. I created blueprint using class A but im unable to reparent old blueprint to class A

funny thing is in the old and new project file names are the same.
weird bugs
