Unable to open Material/Mesh/Blueprint Editors

After import of my mesh (fbx) into project I tried to open it in the editor by double click on the mesh in Content Browser and nothing happen. And after that I couldn’t open any additional editor like Material or Blueprint Editor. I reinstalled engine twice, changed version from 4.21 to 4.20 but it won’t help.
