I think the problem was because internet connection, because my internet connection was slow at first time i open the project there was an error, i ignore it. And after i open the second time, it become like the screenshot.
Open a new unity project, connect to Plastic SCM, then close
Then open the old project where you had the problem and it should work!
I found the solution. Sorry.

The people at Unity are such clowns sometimes.
PlasticSCM is owned by Unity Technologies, it should work with Unity!
Ridiculous.
