Time and SetActive class, what's wrong with them?

Question

C++ / C#

Hello. Pause question. I have a button that should do the following:
1. Turn on the pause panel.
2. Call the function
public void Pause()
{
Time.timeScale = 0f;
}
It includes a pause, but the panel remains inactive.
I tried to turn it on from the script - the link to the socket becomes zero, I tried it from another script - the same situation
Tell me what could be wrong?
