Hi,
Does anyone have an idea what might cause this exception?: [2022.11.13-12.57.27:572][598]LogWindows: Error: Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000180

At first I’ve thought it’s something in the code obviously, but only lines below are like this: [2022.11.13-12.57.27:572][598]LogWindows: Error: [Callstack] 0x00007ff635f83a1d DarknessReborn-Win64-DebugGame.exe!UnknownFunction []

So not really pointing in any specifing line in code. I’ve searched a bit and on one of levels in my projects it has stopped occuring after I’ve deleted a planar reflection actor (I have planar reflections disabled in the project because when you have MetaHuman it it, project can’t be packaged for some reason).
However, after that, it has also occured on an other map, where there are no planar reflection objects.
Another thing to consider is that it only happens on packaged builds (both Shipping and Debug versions), but not in Editor.

Does anyone have an idea what kind of sorcerery is this?
I’m also attaching log from crashed game on the map without planar reflections type object, if that could help. The crash is at the end of the log, obviously :smiley:

Found this in the log:

Script Msg: Attempted to access index 14 from array 'Sound' of length 2 in '/Game/Developers/Vul/BP/BP_Music.BP_Music_C'!

Maybe the exception was throwed because of the blueprint trying to access an object/item that doesn’t exists.

Try to check the array length before use an item from it in this blueprint and test again. :eyes:

Thanks for answer!
I do not however think this is the cause- as you can see it happens multiple times in the log, if that would cause crash I think it’d happen only once before crash
