ue5 crashed when using kawaiiPhysics and ControlRig in levelSsquence

[15128582506]

SkeletalMesh use kawiiPhysics in Levelsequence. If I add ControlRig(or FKcontrolRig), UE will crash. I have encountered this issue in both UE5.1 and 5.2.

CrashReporter : Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x00000000000000c0 UnrealEditor_KawaiiPhysics!FAnimNode_KawaiiPhysics::Initialize_AnyThread()

Is there any way to solve this problem？

Hi,@pafuhana1213

Unreal Engine Version Used：5.21(epic) kawaii physics Version: 00230523-v1.11.0

You can try this step: 1.create a new project ,add Kawaii Physics to Plugin folder(Reduce interference from others) 2.add Content to the ProJect :Third Person(In order to get a skeletalMesh) 3.create a new Animation Blueprint and choose SK_Mannequin to bind it 4.add Kawaii physics Node 5.create a new Level, add a new Level Sequence, add SKM_Manny in Level 6.set SKM_Manny Details : Animation Mode chose Use Animation Blueprint; Anim Class chose NewAnimBlueprint( stpe 3 created) 7.open Level Sequenc(step 5 created),in Sequencer Windows add Track chose SKM_Manny(add skeletalmesh track will auto add FKcontrolRig track)

Then, the Unreal Engine will crash.

The order of steps 6 and 7 can be reversed.
