I am working in UE5.2 and I have an actor component that crashes when I compile the event graph. Nodes don’t even needs to be connected for it to crash and its currently empty. I do have functions set up in the actor component and I can compile the functions. I can even change the functions then go to event graph and compile and its fine but adding to the event graph crashes unreal. I’ve tested other actor components and they have no issues its literally just this one in particular dose anyone have any suggestions on what I can do to fix it apart from making a new actor and starting again ? the error code is

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000000000030

Did you ever figure out what’s causing it? currently having this problem with a actor component, as you said functions in same actor component work fine, event graph in every other thing works fine.

Even if i add a “print string” that isn’t connected to a event and try to compile, ue5 crashes.

I ran into the same problem and was able to fix it by adding a Node to the event graph (I just did a empty custom event) I then saved it without compiling it. Then still without compiling I closed out of unreal and reopened my project and for some reason it fixed the issue. I hope it works for you as well!

Got the same problem and fixed it by saving the nodes and then compiling. After that, my UE5 crashed again, but after a restart, it worked.
So it’s just works (c) Todd Howard
Hope it works for yalls too.
