Hi @Ajay Singh2 ,
This is a common and a known issue , it usually take 3-5mints to present the CI class manager work area. This is because that section has to load whole lot of data behind the scene.
Some times the even after a wait time you get nothing on the screen. Try clearing system cache and reopen it.
For smooth fix raise a HI case this may be related to performance and data.
