Hello! I am having this issue in my dump file:
The thread tried to read from or write to a virtual address for which it does not have the appropriate access
0xc0000005
My Packaged Game is crashing only when I create a new game and try to make a new game save file. Any Ideas why? Does my system not have write access for some reason? Can I change that? It is not just on my Desktop. Laptop as well.
Without seeing the full error and its stack we can only guess, it might be a file access violation or maybe just a null reference error.
You can check the crash folder for more information on the crash, it’s located in the Saved\Crashes folder. CrashContext.runtime-xml will have a lot of info in it.
For Development builds that folder is in the game’s folder, for Shipping builds that folder is at C:\Users\{your username}\AppData\Local\{game name}\Saved\Crashes.
You can also try attaching to your game after launching it with Visual Studio (Debug → Attach To Process…) and then trigger the crash.
Visual Studio will better show you what’s happening when you encounter the crash.
Thanks for the reply!
I will attach the log file for the most recent crash. In the meantime, I will try attaching the process and see if I can evaluate the issue from CrashContent.runtime-xml

Hmm odd, seems it can’t find an IK solver in one of your IK Rig assets. I would check the asset that it’s sending to that function to see if something is wrong with it. Check its path, find it in your project, potentially even recreate it if needed.
This might also have been fixed in UE 5.2, you can check if upgrading to that fixes it.
If nothing helps then I would try to make a minimal repro project with only the crashing asset and send it to our bug submission form.
Remaking my IK rig solved the issue. Must have been an old reference!
Thanks for the help!
