Can't Package or Cook Unhandled Exception 0x0000000000000000

New to ue5, trying bunch of things, I stopped packaging and testing stuff for a bit, “it works in editor, must be fine” I thought. But apperently not, if the project is saveable I want to save it, I don’t really see why would it break.
Can’t cook or package the project.

I tried:
Verifying EU5.1.1
Disabling “incredibuild”
Removing saved game’s I did during editor tests
Resetting nvidia to default settings
“Fixed up” bunch of “redirectors”

the error I got starts with this:

LogWindows: Error: begin: stack for UAT
LogWindows: Error: === Critical error: ===
LogWindows: Error:
LogWindows: Error: Fatal error!
LogWindows: Error:

0x0000000000000000 looks like a very basic error code, but I couldn’t find much about it.
Anyone knows what could be the problem? Or maybe its bugged and Im trying things for no reason.

I been going over the blueprints and notices something weird:

How is both my GifVisibilityTest Actor and TeleporterCave Actor have the same folder???
What is going on, is this why my game can’t package stuff possibly ?

The error message you are seeing indicates that the Unreal Engine Editor encountered an access violation while attempting to read memory at address 0x0000000000000000. This type of error can occur for a variety of reasons, including corrupted memory, invalid pointers, or other issues with memory management.

The best solution is to remove content which you think can cause issues like these. Start by seeing if you can package the game if it only uses a blank level and continue to add on other content to see if there is something specific causing the issue. This could be a plugin or imported content from your PC or the Marketplace.
