Telegram bot - endless event call, after clicking on the inline-keyboard, what is the reason?

Question

PHP

After pressing the keyboard of the "inline_keyboard" type, the client gives the inscription "Loading ..." on top,
and starts to lag everything, and endlessly "poke" on this button, which leads to spam in response.
Until you click on another one.

This happens with any inline keyboard button. So only in my bot, in others - everything is fine.

For example:
1) I press the button "FAQ - frequently asked questions"
2) The client receives a message from the bot "BLABLALA HELP".
3) And this message begins to be sent to the client endlessly. And the inscription "loading ..." on top - does not disappear.

Here I press the button in the usual keyboard "Support". (With a normal keyboard - no problem)

The bot sends a message with an inline keyboard. In it, for example, I click "FAQ".
And this is where the spam starts.
