[BUG?] UE5.4 crashes when trying to open the animation retargeted from old mannequin to MakeHuman model

Steps to reproduce:

1. MakeHuman can be downloaded from here.
2. Create any model with skeleton “GameEngine” and export it as FBX in T-pose.
3. Import it into Blender, do some operations such as renaming materials, replacing textures etc. and export as FBX again. (I don’t know if this step is important but I had done it.)
4. Import that model into UE5.4 with blank skeleton; this will automatically create the new skeleton.
5. Right-click any animation of old mannequin and click “Retarget Animations”.
6. The source mesh will be chosen automatically; choose the created on step 3 MakeHuman model as the target mesh.
7. Click “Export Animations” and confirm.
8. Double-click the created animation and enjoy the crash!
   @SupportiveEntity, could you clarify is it a bug, or why the editor crashes? It is strange at all that the editor can crash on something except the overflow of hardware resources: does the engine not have try-catch?
