No, I use Magic Bone UE5 Rig Creator.
Same here! Hoping for a solution!
Getting this exact same crash. Fresh project, trying to import a Manny skeleton with new bones does this, even if its just 1 bone

Hey,
I am getting the exactly the same error,
Did anyone find a solution to this?, as its critical to my work and little worried this is bug.
Same here, I am also experiencing the same error message/issue, and my unreal engine crashes right after.
Anybody knows if this is fixed in 5.1.1?
Same problem. No solution so far.

Not sure if it’s the same problem, but looks similar:
Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Containers\Array.h] [Line: 763] Array index out of bounds: 0 from an array of size 0
UnrealEditor_OpenXRHMD
Same kind of problem here:
Still no news about how to correct this? The project couldn’t build under 5.0.3, and same here after migrating it to 5.1.1

I’m getting the same issue on a recently upgraded project too. Trying to figure out the issues.

I managed to fix mine. Had some C++ code using an array. It was accessing something before it had been created. Hope it helps!

How long do we have to wait for this bug to be fixed?

I have ran into this a couple times, and my fix has been to remove the blend profile FastFeet and weight blend profiles that are on the mannequin skeleton. There is not a clean handling of bones beening added but not represented in this profile on skel mesh import. These profiles are used in ABP nodes in certain cases for blending. It is a nice feature but needs a bug fix for bone additions.
It is also my understanding that this is now fixed in 5.1.1
Hope this helps.
Similar error ,no c++ and doing no anim work at all. Was however, using modeling mode.

Hello, Right click on my static model that I repeat the most in the scene and select Nanite and mark, then compile only lights and the error went away, I hope it works for you.
me too exact same error -im using VR and animation, seems to happen if i take off and put on the HMD a few times
