It looks like you haven’t “activated” your license yet. Open eLicense Control Center and enter the activation code which should be in the box.
When you activate it it should update you license to 10.5 under the Grace Period.

But i look my elicense control center there have my licenses - Cubase 10 Pro. I did it . But what is problem ?

If you have a right to the grace period upgrade, it will activate when you run maintenance in elicencer control center.
