Packaged game crashing on level transition (Ensure condition failed: GetShadowIndex() == 0)

Hello all,
I’ve been struggling with this issue for around a month now with no end in sight. Any help will be greatly appreciated.

After upgrading my project from 4.24 to 4.25 my game keeps crashing upon changing level when playing the packaged build, but not in the editor.
The crash is random, I can sometimes change the level 2 times or 20 times before a crash.
The error I get initially is either blank, or looks like this:

I’ve tried a lot of things but I can’t seem to figure this out,
Here is the crash context:

<ErrorMessage>Assertion failed: ComponentsThatNeedEndOfFrameUpdate.IsValidIndex(ArrayIndex) [File:D:/Build/++UE4+Licensee/Sync/Engine/Source/Runtime/Engine/Private/LevelTick.cpp] [Line: 863]

</ErrorMessage>

And here is the debug text document with the crash:

If you need any more information I’ll be happy to give it (I’m kind of a noob with this sort of thing)

Thank you for any help, it’s greatly appreciated!

I have the exact same problem. Anyone have ideas?
