Problem with an additive layer.Apply = crashes ue4

Hello,

I have a problem turning a bone into an additive layer. Once the key is done, pressing apply systematically crashes ue4.

I posted a video to show you the problem.

I tested with a blank project and the problem still appears.

I specify that I use mixamo retarget animations with the assets of synty I use the ue4 4.25.4
