Hello Lovely People!
I'm trying to open the 2D Physics examples with version 3.0.2: (Specifically the one with the Kinematic body) and tried 3.0 too
But no way it's just die while importation, The particle 2D example doesn't work too.

weirdly there are some projects that work fine the like Platformer 3D, Kinematic Character 3D,
2D lighting and the Isometric game
