Thanks for the update! I’m assuming you are talking about the Blueprint/Game and Blueprint/Player folders? Were you only able to open them if they were in a new project? I’m a little confused on what you actually were able to open? Did you remove those two folders and open the original project or did you pick out those two BP’s mentioned above from the original and were then able to open it? Also if it would help to see inside those BP’s to try and figure out why those are crashing let me know.
