Bug / Crash Post Unity 2019.1 error

[witskho]

Thanks for the answer. Unfortunately, re-initialization and re-creation does not help. I do not update the old project, and I work in a completely new, created already in the 2019.1 version. For clarity, recorded video in a completely clean project, where there is only a model and obi asset. What am I doing wrong? Same situation with other models with skin, which worked in the 2018 version, so this is not a problem of specific model or geometry. After recording, I tried to use other import options. After each change, I did re-generation and re-initialization every time. It did not help.
