FKContolRig::VM and FKControlRig:DynamicHierarchy crash game in packaged game

[Rewriter00x]

I have packaged WindowsClient and WindowsServer for our game. One of our animation blueprints control rig node uses FKControlRig. When calling this animation node in package I get this log in client on crash

Does anybody know what is the problem with this?

[Benyamin3000]

that just happened to me. Hope someone knows a solution!

[Ridelrr]

Yup I’m getting this as well. I have one ABP that uses control rig but it gets inherited by a bunch of other ABP’s…

[Benyamin3000]

Hello @Rewriter00x and @Ridelrr
please refer to:

Level Sequence not playing in packaged project

I don’t know if this applies to everyone here but it probably plays in the editor because it was already in ram. The first time you run it it starts loading but isn’t fast enough. The solution is to load it by default. For a sound I have it pre defined in a game mode variable (blueprint>add variable). Maybe sequences work too.

and this tutorial:

Animating In Control Rig - How To Bake Animation To An Anim Sequence

and this for solution:

Packaged Game crashes after shortly

Seems control rig in sequencer is cursed Probably just a bug that will be sorted out in future updates. Some people were able to get around crashes with this combination by baking the control rig animation: Here is a tutorial how to bake control rig animations. It’s worth a try at this point [Animating In Control Rig - How To Bake Animation To An Anim Sequence]

hope I could help!

Encountered 2 object(s) breaking Disregard for GC assumptions

Hello! Maybe you already solved it, but I recently had the same problem, exactly the same error!
Next: Actually, it doesn’t have much to do with the animation, as I wasn’t even using IKcontrolRig in the game, but the same error appeared:
Encountered 2 object(s) breaking Disregard for GC assumptions
My animations were all exported via Bake Anim. But what really happened is that the Garbage Collection was removing some object. How did I solve it?
I simply deactivated the ControlRig plugin, (do bake animation first in every level sequence you are using) I did Package again, and it worked, the game no longer crashed.

this is will be crashed
