Hi.

I’ve got so many delegates around my C++ codes and my blueprints. If I don’t compile the codes for multiple times before playing the game, this error pops up and the engine crashes.

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x000000000000016c

Delegates have some problems that I’m pretty sure that my code isn’t causing them because if I compile the codes and then re-run the game, the game runs fine.

Any suggestions?
Thanks in advance.
