Umotion instantly crashes my unity project

I bought Umotion some days ago, and it worked really well, i made some animations for my project, but today when i tryied to open my unity project and tryied to close Umotion project unity crashed, everytime when i try to interact with Umotion it crashes. I thought maybe reason in my Umotion project and decieded to delete it. After that unity started to crash instanly when open project, and the only way to fix this

 to delete Umotion folder from the project. I really like this asset and i hope  it wont take to much time to fix this
