Assertion failed is there a way to fix it? 5.4.1

Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Containers\Array.h] [Line: 758]
Array index out of bounds: 70 into an array of size 70

I almost lost working on the project because of this demonic bug. Every time I open specific animation it will instant crash and give me that error.

when you imported that animation asset, did you got any warning in the output log ?
it possible there an issue with the animation asset itself.

No! I didn’t get any message because I only transfer animation from 5.3.2 to 5.4.1.
In 5.3.2 there’s no Assertion failed happen only in 5.4.1 and if I create again another new project from 5.4.1 and transfer the animation and open it it will crashed again. I don’t know why it’s happening in 5.4.1

I read on another topic to try this: update redirections in parent folder and do audit assets as well.
It’s also true that that crash message is everywhere.

Yes! I already try this method but sadly it won’t work still getting crashed.

Check out the output log file inside your project folder > Saved > Logs (just after the crash happen).
should be those on last lines, we might get some hint from there if anything popout useful.

â– â– â– â– . As I said, I have a lot of those in many occasions.
I use Blueprint / C++ so I checked the correct Build Tools from Visual Studio.
Is that your case?
