I tested this and removing “transform bone” removes warnings and compile errors. However i can copy paste same exact animation blueprints to another blueprint and those blueprints can compile without errors. Is there any way to fix original animation blueprint since its going to be a lot of work to redo it ?

Sounds like the same problem here.
