Game object delete itself from hierarchy when I play animation

When I play animation which change offset polygon collider 2D the gameobject with animator destroy itself in hierarchy for no reason. When I remove collider offset the animation start working properly once again but without collider it’s unusable for the game. Until this day it was working properly but suddenly it has broken for no apparent reason. I haven’t change animation in any way. Only thing I did was importing Google Play Service and installing some SDk’s. I was trying to find solution the whole day but came up with nothing and now I am desperate.

Did you delete the game object during recording. Check your dopesheet/curves to see
